Science and Technology Log

As I explained in an earlier blog, all the scientist on the ship are here because of the Atlantic Marine Assessment Program for Protected Species, or AMAPPS for short. A multi-year project that has a large number of scientists from a variety of organizations whose main goal is “to document the relationship between the distribution and abundance of cetaceans, sea turtles and sea birds with the study area relative to their physical and biological environment.” So far I have shared with you some of the Oceanography and Marine Mammal Observing. Today I am going introduce you to our Marine Mammal Passive Acoustics team and some of their cool acoustic science. The two acoustic missions of the team are putting out 10 bottom mounted recorders called MARUs or Marine Autonomous Recording Units  and towing  behind the ship multiple underwater microphones called a Hydrophone Array to listen to the animals that are as much as 5 miles  away from the ship. The two different recording devices target two different main groups of whales. The MARU records low frequency sounds from a group of whales called Mysticetes or baleen whales: for example, Right Whales, and Humpback Whales. Once the the MARU has been programmed and deployed, it will stay out on the bottom of the ocean collecting sounds continuously for up to six months before the scientist will go retrieve the unit and get the data back.  The towed Hydrophone Array is recording higher frequency sounds made by Odontocetes or toothed whales like dolphins and sperm whales. The acoustic team listens to recordings and compares them with the visual teams sighting, with a goal of getting additional information about what kind and how many of the species are close to ship. Even though the acoustic team works while the visual team is working during the day, as long as there is deep enough water, they can also use their equipment in poor weather and at night.

Here are Chris and Genevieve preparing to deploy the MARU.

Science Spot Light: The two Acoustic team members we have on the Gordon Gunter are Genevieve Davis and Chris Tremblay. Genevieve works at Northeast Fisheries Science Center (NEFSC)  doing Passive Acoustic research focusing on Baleen Whales. She has worked there 2 and a half years after spending  10 weeks as a NOAA Hollings Intern. Genevieve graduated from Binghamton University in New York. She is planning on starting her masters project looking at the North Atlantic Right Whale migration paths.  I have been been very lucky to have Genevieve as my roommate here on the ship and have gotten to know her very well. Chris is a freelance Marine Biologist. Chris recently helped develop the Listen for Whales Website and the Right Whale Listening Network. He also worked for Cornell University for 7 years focusing on Marine Bioacoustics. Chris is also the station manger at Mount Desert Rock Marine Research Station run by the College of the Atlantic in Maine. He actually lives on a sail boat he keeps in Belfast, Maine. Chris also intends of attending graduate school looking at Fin Whale behavior and acoustic activity.

Personal Log

So while most adults were worrying about their taxes on April 15th, I was having fun decorating and deploying Drifter Buoys. Before I left for my trip Jerry Prezioso had sent me an email letting me know that two Drifter Buoys would be available for me to send out to sea during my time on the ship.  Drifter buoys allow scientists to collect observations on earth’s various ocean currents while also collecting data on sea surface temperature, atmospheric pressure, as well as winds and salinity. The scientists use this to help them with short term climate predictions, as well as climate research and monitoring. He explained that traditionally when teachers deploy the buoys, they will decorate them with items they bring from home and that we would be able to track where they go and the data they collect for 400 days! The day before I left, I had my students and my daughter’s class decorate a box of sticky labels for me to stick all over the two Drifter Buoys. I spent the morning of the 15th making a mess on the lab floor peeling and sticking all of the decorations onto each of the buoys. Around mid-day we were at our most south eastern point, which would be the best place to send the buoys out to sea.  Jerry and I worked together to throw the buoys off the side of the ship, as close together as we could get them. A few days later we heard from some folks at NOAA that the buoys were turned on and floating in the direction we wanted them too.

If you would like to track the buoys I deployed, visit the site below and follow the preceding directions.

Geographical Area: Southeastern Pacific Ocean, off the coast of Chile and Ecuador
Date: June 1, 2012

Wind speed: 4.7 kt SE
Sea temperature: 24.77 C

We are almost at the equator!  The coordinates of the Galapagos Islands, where Puerto Ayora is, are 0, 90W.  The weather has been warm but a nice pleasant breeze is going all the time – the trade winds, a constant wind out of the southeast. It’s helpful as the ship is heading in the same direction as the wind!  When out on deck, it feels like perfect weather, it’s easy to forget how direct the sun is so close to the equator. Sunscreen is a necessity!  We are approaching the place where every day is an equinox.

It’s neat to think I will be staying at a hotel on the equator (equalizer of day and night.) Students, when I get to my hotel I will check and see whether water goes down the drain clockwise or counterclockwise, as we discussed in science class!

Most of the crew will take the ship to its home port in San Diego after dropping the science team off in the Galapagos. A new team of scientists will be waiting to board. The Stratus Team is crunching away at data gathering and wrapping up our reports.  Thoughts are starting to drift towards scenery of volcanic islands, beaches, giant tortoises and exotic birds which we look forward to seeing very soon!  So the science continues, no matter where you go…but we have a few more days left as sailors!

The crew tries to arrange some fun on occasional nights as we have to make our own entertainment…there is no TV and very limited internet (quite slow when it works!) and of course, no leisurely phone calls or text conversations from out here in the deep blue.  Sometimes it’s a movie – North by Northwest (a theme – our direction of travel), City of God, and a North Korean movie none of us had ever seen, as well as a poker game.  Most of us have books we are reading, but it was a big surprise that there is a fantastic library here! It has a few dozen shelves of books, mostly fiction, something for everyone’s taste. I’ve already read two books and have started a third.

Melville's library

There are about twice as many books than are shown in this picture! The library also has a TV and DVD player for watching a movie.

There are few books on the Galapagos Islands floating around and we have all been skimming them to decide how we will spend our time when we arrive in port. Many of us like to listen to our iPods and I have mentioned before, spend some time exercising.  Photography is a shared hobby, too, and now that our cruise is nearing an end, there is a lot of photo sharing going on. A few crew members find some spare time to fish from the side as we move forward. The ones that have been caught were shared at mealtimes. I especially enjoyed the yellowtail!

Being on a ship for a couple of weeks has also given me a look behind the scenes for every shipment of imports that comes across the seas to ports in theUnited States, such as Brunswick, Georgia. Each cargo ship has a crew of people bringing the goods over safely, loading and unloading, and doing it again. We have traversed over 2,000 miles and done it in excellent weather. The shipping industry and the goods my family and I use is something I had not given a second thought to before.  I have a new appreciation for the maritime industry.

Science and Technology Log

Since deploying the moored buoy, we have put quite a few drifters in the water including the one I personalized for our school!

Launching a drifter

Elsie and Jamie launch a drifter, one of many data gathering instruments that will drift with the current and report ocean temperature, and its location is tracked online.

Since we are getting closer to land, there is a higher likelihood of finding fishing gear in the water, so we have to be on alert for that at all times. We don’t want our instruments to get tangled up in the long lines fishermen leave in the water hoping for a catch to come along.  One day, the ship did run into some long lines and had to stop and make sure it wasn’t in the propellers. Another very cool instrument we’ve been deploying are ARGO drifter floats http://argo.whoi.edu/argo.whoi_about.html – Think of a scientific instrument that will measure temperature, conductivity (salinity)  and depth and that can be programmed to move around at different depths, GPS keeping track of its location for several months or even years.  They have computer processors in them and a little motor that “drives” it deeper or shallower as the need for data at certain coordinates dictates. Here is a diagram of the ARGO drifters we have been launching. http://argo.whoi.edu/argo.whoi_components.html

As the data from last year’s Stratus 11 deployment is analyzed, plus the hourly data from our UCTD profiles, several trends have become evident. I have also been able to get a look inside some of the instruments. Can you imagine sending a tablet computer hundreds of meters into the ocean? That is exactly what has been done. In the photo, you can see an example of an instrument that measured ocean currents for a year at great depth and pressure.

Gathering data from the mooring

Sean Whelan downloads the data from instruments and then prepares the instruments to be shipped back to Woods Hole.

Seaguard Current meter picture

Collecting data from a current meter using the touch screen and stylus, this instrument has withstood a year of underwater conditions on a card like you keep in a digital camera.

There is also redundancy of instruments (more than one) in case one fails or the battery dies, which sometimes does happen. Regarding the trends – the science team has anticipated this, having seen it similarly each year, these are their hypotheses as the Stratus experiment continues.  As we near the equator, the salinity is rising – there is more evaporation when the sun is more direct. As some of the ocean water becomes humidity in the atmosphere, the salt is left behind in the ocean, as salt does not change to a vapor in our atmosphere – it is left dissolved in the ocean and thus increases the ocean’s salinity. A “big” increase in salinity would be 1 part per thousand in a small area, for example, so we are tracking the trend of small changes. In the hourly UCDT deployments we have been conducting, we have measured between 34.08 and 37.7 parts per thousand.

Checking data in the main lab

Bob Weller and Sebastien Bigorre check the monitors for the status of the multi beam sonar display.

Oxygen content is important for all life as well as for many practical applications.  The absence of oxygen (or lower amounts) allows other chemical reactions to take place in the water.  The formation of certain acids becomes possible, which is deadly for some organisms, and favorable for others. An example we saw of this was a piece of hardware that was on the mooring cable had a very low oxygen levels, had sulfuric corrosion on it.

Another measure important to scientists is fluorescence which detects the amount of phytoplankton in the ocean – small organisms at the base of the ocean food web which use the CO2 to reproduce.

Society has great dependence on the ocean to absorb the right amount of carbon dioxide in the atmosphere, but at a certain point, the ocean chemistry will change and affect this balance of life. Climate prediction allows us to keep the pulse of the stability of this balance and all of this data we have gathered is part of the scientific puzzle of climate prediction.

An interview with the Captain, Dave Murline

SO: How long have you been a ship captain?

DM: Since 1994. Since then there has been an increase in  paperwork, regulations and inspections due to a world-wide push to make going to sea safer.

SO: What kinds of skills are necessary?

DM: You need a well rounded background in Seamanship, good people skills and the habit of treating everyone with respect.

SO: Does being on a science research ship bring any specific/different expectations than being on another type of merchant ship?

DM: Yes, on a research vessel, you are dealing with scientists and their instruments as opposed to general cargo. Every voyage is different and brings on its own set of new challenges. Scientists tend to work outside of the norm so there are always new ways to figure out how to use the ship in the best way that we support the mission. This is a job that always keeps me thinking and using my imagination!

SO: We are in the middle of a huge ocean, and our destination – a buoy – is like a pinpoint on a map. What has to be considered to make sure you get to the exact location?

DM: We need to consider weather, currents and also vessel traffic around the area. Some hazards to navigation are reefs (shallow), islands, clearances to foreign countries EEZ (Exclusive Economic Zone within 200 Miles of any country), and pirates. Once I encountered pirates on the Arabian sea, but on a ship like this, were able to out maneuver them. We have not gone back there!

Melville Captain

I’m on deck with Captain Dave Murline who is cooking up some freshly caught yellowtail. If you like to fish, a side benefit is when you get to enjoy your hobby!

SO: Have you ever gotten lost?

DM: I’ve never been lost at sea, but get lost sometimes driving around in my hometown!

SO: Can you name a really interesting research cruise you have been on?

DM: Every voyage is unique and interesting. I’m always looking forward to the next mission and challenge. Our work varies from studying the atmosphere sea interaction to marine mammals. There is so much to learn about our oceans, it is all very fascinating.

SO: What is something most people don’t know about your job?

DM: There is tons of paperwork with my job! That is what I consider the “work” part. Also, along with many other responsibilities, I am the ship’s medic which can be a “scary” part of the job as we are often working far away from any medical facilities. That is why “Safety” is our number one priority on any cruise.

SO:  Thanks for letting us get the inside scoop on being the Captain of the R/V Melville!

****************************************************************************

There are so many interesting people on the ship with a variety of skills. We eat all meals together and many of the crew support the science team in different ways. They are from many areas of the country and it has been great to get to know them!

My work out routine has become more varied – Unfortunately, the noise with mineral spirits/paint odors are a package deal along with the stairmaster in the machine shop, so I found another way to get some exercise in after noticing what some of the crew did. I spent about an hour doing many laps around the ship, up and down all the stairs of the outdoor decks, with the beautiful ocean all around me. For entertainment, I not only had my iPod, but for added visual interest, all kinds of valves, winches, life preservers, hoses, and the occasional engineer fixing something. A good line from my music today – I sing my heart out to the infinite sea! (The Who)

There is a little store on the ship that has been locked up tight. All of the guests on the ship are anticipating the sale in the ship store tomorrow!  There are t-shirts, hats, and other items as Melville souvenirs.

A successful but slimy recovery!

The Stratus 11 Buoy was successfully recovered in a process that began before breakfast and lasted into the evening. Remember the thousands of meters of cable?

First, a computer command triggered the acoustic release of the anchor.  There is not a way to safely recover this anchor, so it is left on the ocean floor. Once released, the bottom of the cable, with all 80 plus of the glass balls for flotation, gradually make their way to the surface.  So when we came out after breakfast, the yellow encased glass balls were all bobbing on the ocean’s surface.  A few folks had to go out in the life boat so the chain could be attached to the ship’s crane, then we started reeling them in. A beautiful rainbow was in the sky like a special treat for us!

Life boat and yellow glass balls

Sean, Eugene and Rob hold onto the deepest part of the cable which has surfaced, thanks to the glass balls encased in yellow cases.

Sometimes one or more will implode due to the massive pressure, and this time, only two did. Little by little, as the cable was wound onto the winch, the instruments started coming in. The deepest ones come in first and the shallowest ones last, opposite from deployment. They were cataloged and cleaned and if all is well, will be used next year on Stratus 13. It is amazing how all of these sensitive tools can last for a year under such conditions!  The battery left with the buoy is good for up to 14 months.  Sometimes, there would be fishing line entangled with the tools, as there is some good fishing in this area. As we started to get to the more shallow instruments – and by this I mean 150 meters or so – we started seeing that organisms had started taking up residence on them!  This is called a fouling community.  There are slimy growth algae and these little shells with a neck called gooseneck barnacles, sometimes with a crab in the shell. The closer to the surface we got, the population of these barnacles just kept increasing and increasing! There were quite a few instruments that were so covered in the barnacles; you could not even identify it!

Nan Galbraith

Nan’s organizational skills help the team know which instrument provided what data to maintain the integrity of the research.

Stratus 11 and its detritus and barnacles

Wearing a coating of fouling organisms, the Stratus 11 buoy looks nothing like the one we deployed 2 days ago! This is typical after a year in the ocean.

Stratus 11 has been successfully recovered, barnacles and all! The crane carefully hoists it onto the aft deck. Photo: Rob Ball

As we recovered more instruments, we were drawn closer to the old buoy, which had acted as an artificial reef for the past year. Whales sometimes like this, so once again, we spotted our cetacean friends! Once the last instrument was on deck, it was time to recover the actual buoy. Like earlier in the day, we needed a few folks out in the boat to help make sure the buoy stayed with the ship and did not float away, as we had released it from the crane. It took longer than expected, but it was finally on board and it, too, had its own fouling community.

All hands were needed to help clean the instruments.  At first, it was a novelty to see a cute little crab crawl out of a colorful barnacle shell, but then all of us became quite ruthless, ripping and scraping them off of the tools with no regard for the destruction of their little ecosystem. We had quite a pile to get through and had no time for this – what was at first cute was not only annoying, but downright nasty!

Cleaning the shallow instruments was the messiest of all! Jamie from NOAA and I tackle a couple of more instruments, with a plethora of barnacles at our feet.

Some folks’ clothes were so disgusting, so caked with grime and detritus of the sea that it was decided to sacrifice them to the great Pacific instead of potentially fouling the ship’s washing machine. With all of the great attitudes and camaraderie, it wasn’t too bad to be doing this clean up together as a team.  All felt a great satisfaction at seeing two facets of the mooring project – the deployment a couple of days earlier and now a successful recovery with no injuries or loss of instruments.  A good nights rest was in order!

Getting ready to clean some instruments

You saw it here first… The EM122 Multi Beam sonar mapped out some brand new ocean floor for future research and deployment. The newly mapped area is seen on the screen – and in a year or so, will be added to the mapping database on Google Earth. So, before this part of the ocean floor makes its mapping debut to the world, you get an insider’s sneak preview here!

Science and technology Log

I’m seeing for real that being a research scientist can be really exciting and hands-on when working out in the field. In our routine of launching UCTDs every hour while steaming towards our target, more acquisition of ocean data takes place in other ways. At certain coordinates, WHOI deploys drifter buoys that monitor ocean characteristics as they drift with the current.  The data can be followed on line not only by the scientists, but by the public!  Two were launched this morning on our watch at coordinates 21º S,  84º W.  And one of them is Kittredge’s adopted buoy!  It is serial number 101878. As you can see in the video clip and photo below, I’ve made sure a little bit of Kittredge Magnet school is left here in the Peru Basin of the Pacific Ocean, where it is about 4,400 m in depth.

Sue with the buoy

It’s time to launch the drifters! All the fish that see this will know about our school!

KMS went swimming in another way, too – my KMS hat flew off my head while working on the aft deck. (Sorry, Mrs. Lange!) Science Rocks in the South Pacific!

The team did a second CTD deployment – this one to the bottom, about 4,500 m.  This is precise work, to analyze maps and bathymetric data to be accurate to find the depth at which it is desired to anchor the Stratus 12 buoy. Keith, Jamie and I were “spotters” with the rosette as the crane lowered it down. Pamela, who is studying phytoplankton, retrieved samples of water with organisms from this deployment.  However, due to customs in Ecuador, it is tricky for her to get her samples back to Chile. Ecuador does not allow anything into the islands that may potentially contain anything living thing, even a sealed sample of water containing plankton. So the samples will continue with the ship to San Diego and then be shipped to her in Chile.

We made it to the old buoy! It was exciting to see Stratus 11 come into view. The bottom area was surveyed in great detail within a few miles of the Stratus 11 to confirm Seb’s chosen spot for Stratus 12.

Dr. Weller and crew

Dr. Bob Weller and Jeff Lord have a pre-deployment meeting with the captain and some key crew members who will be assisting.

The next day, the deployment of the new mooring, Stratus 12, is a full day of coordinated teamwork – about 4,500 m of cable with 2,000 m of instruments. The first 50 meters at the surface has 20 instruments!  It took over 8 hours to put the buoy and all attached instruments in the water, and that is after hours of assembly on the aft deck.  One new instrument added was at the deepest part of the ocean in this area and will provide data on deep ocean temperatures and salinity, something currently missing from climate models.

Stratus 12 is in the water!

We enjoyed perfect ocean and weather conditions on the day of the launch! The Stratus 12 buoy is in the background behind me.

Anchor splash

After the last instrument is placed on the mooring line, its anchor is sent down. At 10,000 lbs., the anchor drop makes a really big splash!

The glass balls go on the mooring line

All hands are on deck to contribute to the mooring assembly and launch.

The all night watches are not over, though – we must continue to collect bathymetric data to map the ocean floor around here. Only about 5% of the ocean floor is actually mapped, and when the team returns next year, they may not be on the same ship. Not all ships have the same sophisticated multi beam sonar as the Melville. Those on watch are actually watching the sonar monitor display as the ship engages in the “mowing the lawn” technique to create a detailed map. The Melville will “hang around” in this area for a couple of days before we remove Stratus 11 from the water. This allows time for data to be transitioned from one buoy to the new one. I am told recovering the buoy is going to be some dirty, grimy work!

Why here, anyway?

The area off the coast of Pacific off Northern Chile and Peru has been historically difficult for climatologists /meteorologists to model.  To predict climate, varying parameters of atmospheric conditions are fed into a computer to simulate what the outcome will be.  The predictions made are then compared to actual conditions to determine the reliability of the computer model. Meteorologists have not been able to accurately predict this region: the actual ocean conditions are much cooler than the computer predicts.

Another finding showing the importance of this area is that when the type, thickness, and altitude of clouds in the Northern Chile /Peru basin are changed for simulations, almost the whole Pacific Ocean’s heat distribution is in turn affected! Satellites gather data remotely, but the constant stratus clouds block satellite data transmission, so it is just not reliable. Data must be collected right here. Given that oceans cover 71% of the planet, and the Pacific is the largest, fully understanding this region is critical to building accurate climate models. Therefore, the Stratus research brings us to 20º S 85º W.

Personal Log 

Animal life has been spotted! On two days, we saw whales! One – perhaps a Blue Whale – was far away and just its fluke was seen.  The next day we had two whales swimming close to the ship, and we were able to watch them and hear them breathe for a while.  According to the crew, seeing whales in this area is rare. It’s odd to be in a body of water teeming with life and see so little of it. We also encountered only one boat, a Spanish fishing vessel.

Bob and Mark continue to feed us well.  The food storage area is below the main deck and they use a dumbwaiter to bring the food up to the kitchen where it is prepared and served. There is food from all over the world; the ship was in South Africa before reaching South America. All of the meat is from South Africa and also some of the coffee. One night, we had some kudu meat – like steak, but from antelope. It was very good, and tasted like bison. Every country’s Customs sends agents to inspect the food service area while in port. The U.S. Customs is very strict and will not allow foreign food into port, so maybe that is why they are feeding us so much!

The cooks work at least 10 hour days. Bob has been a cook for 21 years and his favorite part of his job is getting to travel.  Mark, our other cook, has been in this job for 10 years. Both of them work for Scripps, as it operates the boat.

Here’s how much we have been eating daily – 7 dozen eggs, 5 heads of lettuce, 5 gallons of milk, and there are NEVER any leftovers! The kitchen always keeps some of the meals for the “midnight rations” so those who sleep in the daytime and work on the night shift from midnight to 8a.m. do not miss out on any of the good fixins.

Finally, I am used to the noise and can sleep pretty well. It’s like I am in a room with power tools being used, even with ear plugs, you can hear the engines.  Everyone here is in the same boat, though (pun intended!). Our next exciting task is ahead, recovering and cleaning up the Stratus 11 buoy.
