Science Log

As I mentioned in my introductory post, the purpose of the SEAMAP Summer Groundfish Survey is to collect data for managing commercial fisheries in the Gulf of Mexico. However, the science involved is much more complex than counting and measuring fish varieties.

The research crew gathers data in three ways. The first way involves trawling for fish. The bulk of the work on-board focuses on trawling or dragging a 42-foot net along the bottom of the Gulf floor for 30 minutes. Then cranes haul the net and its catch, and the research team and other personnel weigh the catch. The shift team sorts the haul which involves pulling out all of the shrimp and red snapper, which are the most commercially important species, and taking random samples of the rest. Then the team counts each species in the sample and record weights and measurements in a database called FSCS (Fisheries Scientific Computer System).

Trawling nets

SEAMAP can be used by various government, educational, and private entities. For example, in the Gulf data is used to protect the shrimp and red snapper populations. For several years, Gulf states have been closing the shrimp fishery and putting limits on the snapper catches seasonally to allow the population to reproduce and grow. The SEAMAP data helps determine the length of the season and size limits for each species.

Another method of data collection is conductivity, temperature, and depth measurements (CTD). The process involves taking readings on the surface, the bottom of Gulf floor, and at least two other points between in order to create a CTD profile of the water sampled at each trawling locations. The data becomes important in order to assess the extent of hypoxia or “dead zones” in the Gulf (see how compounded data is used to build maps of hypoxic areas of the Gulf: https://www.noaa.gov/media-release/noaa-forecasts-very-large-dead-zone-for-gulf-of-mexico). Plotting and measuring characteristics of hypoxia have become a major part of fishery research especially in the Gulf, which has the second largest area of seasonal hypoxia in the world around the Mississippi Delta area. SEAMAP data collected since the early 1980s show that the zone of hypoxia in the Gulf has been spreading, unfortunately. One recent research sample taken near Corpus Christi, TX indicated that hypoxia was occurring further south than in the past. This summer, during surveys two CTD devices are being used. The first is a large cylinder-shaped machine that travels the depth of the water for its readings. It provides a single snapshot. The second CTD is called a “Manta,” which is a multi-parameter water quality sonde (or probe). While it can be used for many kinds of water quality tests, NOAA is using it to test for hypoxia across a swath of sea while pulling the trawling net. This help determine the rate of oxygenation at a different depth in the water and across a wider field than the other CTD can provide.

Did You Know?

Algae is a major problem in the Gulf of Mexico. Hypoxia is often associated with the overgrowth of certain species of algae, which can lead to oxygen depletion when they die, sink to the bottom, and decompose. Two major outbreaks of algae contamination have occurred in the past three years. From 2017-2018, red algae, which is common in the Gulf, began washing ashore in Florida. “Red Tide” is the common name for these algae blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae. The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events. The wave of hurricanes (including Irma and during this period caused the bloom. The second is more recent. Currently, beaches nearest the Mississippi Delta have been closed due to an abundance of green algae. This toxic algae bloom resulted from large amounts of nutrients, pesticides, fertilizers being released into the Bonnet Carre Spillway in Louisiana because of the record-high Mississippi River levels near Lake Pontchartrain. The spillway opening is being blamed for high mortality rates of dolphins, oysters and other aquatic life, as well as the algae blooms plaguing Louisiana and Mississippi waters.


Personal Log

Pulling away from Pascagoula yesterday, I knew we were headed into open waters for the next day and half as we traveled east down the coast to the Tampa Bay, FL area. I stood on the fore deck and watched Oregon II cruise past the shipyard, the old naval station, the refinery, navigation buoys, barrier islands, and returning vessels. The Gulf is a busy place. While the two major oceans that flank either side of the U.S. seem so dominant, the Gulf as the ninth largest body of water in the world and has just as much importance. As a basin linked to the Atlantic Ocean, the tidal ranges in the Gulf are extremely small due to the narrow connection with the ocean. This means that outside of major weather, the Gulf is relatively calm, which is not the case with our trip.

Navigation buoy

As we cruise into open waters, along the horizon we can see drilling platforms jutting out of the Gulf like skyscrapers or resorts lining the distant shore. Oil and gas extraction are huge in this region. Steaming alongside us are oil tankers coming up from the south and cargo ships with towering containers moving back and forth between Latin America and the US Coast. What’s in the Gulf (marine wildlife and natural resources) has geographic importance, but what comes across the Gulf has strategic value too.

The further we cruised away from Mississippi, the water became choppy. The storm clouds that delayed our departure the day before were now overhead. In the distances, rain connected the sky to sea. While the storm is predicted to move northwest, the hope is that we can avoid its intensification over the Gulf Stream as we move southeasterly.

Choppy seas
Choppy seas as we cruise across the Gulf to the West Coast of Florida to start our research.

I learned that water in the Gulf this July is much warmer than normal. As a result, locally produced tropical storms have formed over the Gulf. Typically, tropical storms (the prelude to a hurricane) form over the Atlantic closer to the Equator and move North. Sometimes they can form in isolated areas like the Gulf. Near us, an isolated tropical storm (named Barry) is pushing us toward research stations closer to the coast in order to avoid more turbulent and windy working conditions. While the research we are conducting is important, safety and security aboard the ship comes first.

Science Log

Day one of my trip and we are delayed leaving. Growing up in Oklahoma, you think you know weather until one of the NOAA fishery biologists assigned to the ship provides you a lengthy explanation about the challenges of weather on setting sail. As he put it, the jet stream is throwing off the weather. This is true. Studies have suggested that for a few years the polar jet stream has been fluctuating more than normal as it passes over parts of the Northern Hemisphere. The jet stream is like a river of wind that circles the Northern Hemisphere continuously. That river meanders north and south along the way. When those meanders occur over the Atlantic and the Pacific Oceans, it can alter pressure systems and wind patterns at lower latitudes and that affects how warm or raining it is across North America and Europe. 

This spring in Oklahoma, it has led to record-breaking rains that have flooded low lying areas across the Great Plains and parts of the southeastern United States. Thunderstorms have generally been concentrated in the southern and middle section of the US as the jet stream dips down. The NOAA biologist also indicated that the delay in our departure could be blamed on the El Niño effect. 

El Niño is a natural climate pattern where sea water in the central and eastern tropical Pacific Ocean is warmer than average. This leads to greater precipitation originating from the ocean. According to NOAA scientists, El Niño is calculated by averaging the sea-surface temperature each month, then averaging it with the previous and following months. That number is compared to average temperatures for the same three-month period between 1986 and 2015, called the Oceanic Niño index. When the index hits 0.5 degrees Celsius warmer or more, such as right now, it’s classified as an El Niño. When it’s 0.5 degrees Celsius cooler or more, it’s a La Niña. During an El Niño, the southern part of the U.S. typically experiences wetter than average conditions, while the northern part is less stormy and milder than usual. During a La Niña, it flips, with colder and stormier conditions to the north and warmer, less stormy conditions across the south. However, the El Niño this year has been classified as weak, which means typically the wetter conditions do not push into the Gulf of Mexico region, but exceptions can occur. With the fluctuating jet stream, the El Nino has vacillated between the Plains region and the upper South and regions closer to the Gulf. Thus, the storm causing our delayed departure comes from a weather condition that has been pushed further south by the jet stream.

While these may be causes for the delayed departure, the actual sailing conditions at the time of our voyage are the main concerns. Looking at the NOAA Marine Forecast webpage (https://www.nws.noaa.gov/om/marine/zone/off/offnt4mz.htm), the decision for our delay is based on a storm producing significant wave heights, which are the average height of the highest 1/3 of the waves. Individual waves may be more than twice the average wave heights. In addition, weak high pressure appears to dominate the western Gulf and will likely last mid-week. Fortunately, we are set sail into the eastern Gulf off the coast of Florida. We should be able to sail behind the storm as it moves west. We do have to watch the surface low forming along a trough over the northeast Gulf later in the week. The National Hurricane Center in Miami (which provided weather data in the Atlantic and the Gulf for NOAA) predicts that all of this will intensify through Friday (July 12) as it drifts westward. This will produce strong to near gale force winds and building seas for the north central Gulf. Hopefully by then we will be sailing south of it.

Did You Know?

The weather terms El Niño and La Niña can be translated from Spanish to English as boy and girl, respectively. El Niño originally applied to an annual weak warm ocean current that ran southwards along the coast of Peru and Ecuador around Christmas time before it was linked to a global phenomenon now referred to as El Niño–Southern Oscillation. La Niña is sometimes called El Viejo, anti-El Niño, or simply “a cold event.” El Niño events have been occurring for thousands of years with at least 26 occurring since 1900.


Personal Log

I boarded NOAA’s Oregon II yesterday when the ship was virtually empty. It was Sunday, and we were not set to leave until mid-afternoon the following day (and now Tuesday, July 9). Spending the night on the ship was more comfortable than I had expected. While the stateroom was cramped (I share it with one other crew member), the space is surprisingly efficient. I had plenty of space to store my gear. The bunkbed was more cozy than restricted.

NOAA Ship Oregon II
My first look at NOAA Ship Oregon II.

My first day in Pascagoula, MS was spent learning about the town. Pascagoula is a port city with a historic shipyard. Pascagoula is home to the state’s largest employer, Ingalls Shipbuilding, the largest Chevron refinery in the world, and Signal International, an oil platform builder. Prior to World War II, the town was a small fishing community, but the population jumped with war-driven shipbuilding. The city’s population peak in the late 1970s, but today, there are less than 25,000 in the area. Pascagoula continues to be an industrial center surrounded by the growing tourism industry across the Gulf region to the east and west of the port. The population also declined when Naval Station Pascagoula was decommissioned in 2006. The old naval base is located on manmade strip of land called Singing River Island and is in the middle of the port. The port still maintains a large Coast Guard contingent as well as serving as the home portfor the NOAA Ships Gordon GunterOregon II, and Pisces. The NOAA port is actually called the Gulf Marine Support Facility and is located a block from NOAA’s National Marine Fisheries Service Mississippi Laboratory.

Science/Technology and Personal Log

Hurricane Michael brought a three day delay to our departure. At first, I was a little disappointed that we were not setting sail right away but now I am glad because I had some extra time to explore Pascagoula, familiarize myself with the ship, and slowly meet the crew as they arrived spread out over several days. Plus, the additional time allowed me to start working on my career lesson plan and to prepare a video tour of the ship. I will upload the video to this blog page as soon as it is complete.

On Thursday, Oct 11th at 9:00am, we departed from Pascagoula and headed out into the Gulf of Mexico. I was amazed at how quickly we lost sight of land and at the vastness of this body of water with which I thought I was so familiar. My favorite part was watching the color of the water change from a dark teal to a deep blue.

On the “Plan of the Day” board under schedule it reads “Steam and Dream til Saturday Afternoon” and that is just what we are doing. Our path will lead us north of the Mexican border and south of Corpus Christi, Texas, where we will find our first station. Until then, in between steaming and dreaming, we are getting to know each other and learning about our roles and responsibilities.

 

 

 

 

 

 

Abandon ship drill

Abandon ship drill! Here I am in my survival suit.

For example, today we practiced our Fire and Abandon Ship Drills. While it is a little nerve-racking to think that something like that could actually happen, it was reassuring to see that everyone was well-trained and the operations ran smoothly.

 

 

 

 

 

 

 

 

My first lesson plan will focus on careers available through NOAA. It is amazing to see the variation in the positions and the backgrounds of the workers on this ship. Basically, on the Oregon II there are three types of employees who make up the ship’s complement.

Types of Employees

This graphic illustrates the structure of the employees aboard Oregon II.

I feel like NOAA has something to offer everyone from entry level positions that require no experience to positions requiring years of experience or advanced college degrees. The best part is that no matter where you start there is always room to advance through hard work and certification. I can’t wait to share all the opportunities with my students!

 

Did You Know?

Oregon II has a reverse osmosis system that uses salt water to create the freshwater needed aboard.  The salt that is removed is returned back to the Gulf.

Incomplete weather data as we were docked.

I’m currently sitting on the Oregon II docked in Pascagoula, Mississippi after a long travel day. It’s eerily quiet as the ship disembarks tomorrow at 14:00 and the majority of the crew will arrive tomorrow. I am enjoying the slow introduction to this ship and finding my way around. The OOD (Officer Of the Deck) gave me a tour of the ship that I will be working on for the next two weeks. The majority of crew is on shore for the Labor Day weekend but will return tomorrow as we disembark and head towards Florida. Our plans have changed due to Hurricane Harvey and debris that may be in the waters making the travel in those waters unsafe.

Science and Technology Log

Due to Hurricane Harvey, the area being surveyed has changed so that we are heading East instead of West to pick up the third leg of this survey that ended off the coast of Florida last week. I have been assigned the day shift from noon to midnight and will be assisting the science crew. The mission of this survey is to monitor interannual variability of shark populations of the Atlantic coast and the Gulf of Mexico. Additionally aboard are two scientist that are on board are studying parasites that these animals carry. Carlos and Brett, the two parasitologists, were on the second leg right before I joined. Their leg started on the tip of Florida and ended where we will start.

Seasick? Felt a little queasy after my first night in dock! Decided the best course of action was to take some medicine, eat a big meal and hydrate to help get my sea legs. Everyone has been friendly and welcoming as we get started. The night crew starts tonight at midnight till noon and the day crew, where I am been placed, will start at noon. Hoping for a good night’s sleep!

Science and Technology Log:

NOAA’s mission is three-fold: science, service, and stewardship.  By utilizing fisheries, hydrographic, and oceanographic scientists in the field, NOAA’s goal is to understand and predict changes in climate, weather, oceans, and coasts, while also putting forth a conservation effort towards coastal and marine ecosystems. This knowledge is shared with businesses, communities, and people, to inform on how to make good choices to protect our fragile earth.

The specific mission, for our current voyage, on the Pisces, is to survey fisheries at pre-determined sites throughout the Western portion of the Gulf of Mexico. The data from these surveys will be brought back to the lab in Pascagoula, Miss. and analyzed. Then determinations will be made for future surveys and studies. According to Chief Scientist, Brandi Noble, “These fishery independent surveys increase our knowledge of natural reefs in the Gulf of Mexico. We get a better picture of what’s down there and work with outside agencies to determine how to maintain the health of the fisheries.  Data gathered will be used in future stock assessments for the Gulf of Mexico.”

DSC_1071

Bottlenose dolphins in the Gulf

The methods used to gather data on this cruise are through the use of the camera array and the bandit reels.  The camera arrays are deployed at sites that have been mapped and sit at the bottom for a total soak time of 40 minutes.  This footage is analyzed and processed by scientists to determine what the conditions of the reef are and the species of fish present in the area and their abundance.  This gives a partial picture, but to get a complete and accurate report, fish need to be studied more closely.  The “Bandit Reels” provide a more hands-on approach and allow the scientists to get data on sex, maturity stage, and age of species.  Some of the fish are released after some initial measurements, but the commercially important species are dissected and samples are taken for further lab analysis.  Initial measurements made with anything brought aboard include total length (TL), fork length (FL), standard length, SL (from nose to caudal fin), and weight.

A closer look at the data allows scientists to make predictions on fish populations and growth over time.  Some of the data we got on this trip were for the Lutjanus campechanus (red snapper) and for the Pagrus pagrus (red porgy).

There are several ways to disaggregate the data to determine differences and similarities based on region, time, species, etc.  For our purposes, we’ll make some observations involving probability, proportion, and statistics.

Math Problem of the day: You are a scientist and have brought data back from the Gulf of Mexico to analyze in your lab.  You have three tasks: a) to get an average fish size based on weight (species specific) b)  to determine what the proportion is of the Standard Length to the Total Length of each species (hint: ratio of SL/TL; find average) c) determine the theoretical probabilities that the next Red Snapper will be  >1,100g, and that the next red Porgy will be <1,000g (hint: how many times does this happen out of the total catches?)

Personal Log

I made it! A smooth flight down to Mississippi (which is a new state for me – I’ve never been here). I arrived to sunshine and warm temperatures – OK, downright hot to me, but I’ll get used to it quickly I’m sure. Pamela Bond, the chief scientist on this cruise, met me at the airport and brought me out to the Gordon Gunter. I quickly learned that it is not only Pam who is super nice and welcoming, but the entire crew. I’ll be introducing them more in future posts.

The ship is not at the usual port near the NOAA lab, but at the former naval station, on an island at the mouth of the Pascagoula River. This yard has multiple uses now, as you can see from the pictures below. So not only is the Gunter here, but it has the company of a Coast Guard vessel, and both are dwarfed by a massive oil rig. On the other side of the pier (not pictured) is a USGS vessel and others. There’s a lot going on here!

Gordon Gunter

The Gordon Gunter (right) and Coast Guard vessel dwarfed by the huge Sovereign Explorer (oil rig), an old rig that has been docked here for about a year, waiting for bids to take it apart for scrap .

Across the way is Pascagoula’s largest employer, and Mississippi’s largest manufacturing employer, Ingalls Shipbuilding, with 11,000 employees right here in Pascagoula! I can see ships in various stages of construction.

I have learned a lot about this area in the one day here at port. Two major events have happened here in recent years – Hurricane Katrina (2005) and the BP oil spill (2010). Both events simply ravaged this area. Everywhere we have been in the last day – the naval station, the NOAA lab, the highway – was under several feet of water during Katrina. You’ve seen the pictures. To hear about it from the folks here is profound. The BP oil spill (also known as Deepwater Horizon oil spill), another devastating event, changed the whole NOAA season (as it did for the fishermen and just about everyone else here). All the NOAA ships on the east coast, and one from the west coast, had to cancel their season’s research and congregate down here to be involved as needed, looking for oil, looking for marine mammals, etc. Today we visited the NOAA lab, where several employees are analyzing plankton samples taken from the affected waters. This is five years later, and still very relevant and ongoing data collection! (sorry, forgot to bring my camera to the lab, but I got to check out lots of plankton under the microscope).

my room

Deluxe accommodations!

Backing up now, to my arrival: Pam showed me to my room – I’m surprised that I have my own room! It has a refrigerator, closet, desk, comfy chair, my very own sink, and a shared bathroom with the room next door. And it has a TV – I barely know how to use a TV!

And then Tony, the ET (electronics technician) gave me a tour of the boat. Since then, I have been wandering around, sometimes in circles, trying to figure out the layout. I can tell right away that the food is going to be amazing.

My head is already spinning with some of the details about the equipment and technology. Pam was not sure if we would be launching on time – everything has to be just perfect for a research cruise to start, and if there are any issues, we don’t go. There were two repairs that needed to be made since the ship came to port just two days ago: one had to do with the unit that makes our water, by distilling seawater (very important!), and the other had to do with a malfunctioning gyro, or gyrocompass, needed for navigation (also important!). I wanted to know more about how a gyrocompass works, so I first looked it up on Wikipedia, and then talked to Dave Wang, the NAV (navigations officer). It’s so fascinating – a compass that points true north partly by using the rotation of the Earth. The good news is that both of the repairs are done and we will be launching on time!

Water tank

This large fresh water tank was added after the Deepwater Horizon oil spill.

I just want to share one bit info about a simple piece of equipment on the aft deck. It’s a water tank. I asked Tony what it’s for, when we have the technology to make fresh water. Well, after the oil spill, getting fresh water was a problem, so the tank was added. It was decided that it was convenient to have after it was no longer needed, and is now used for things that need a freshwater wash.

I am wrapping up this blog post now, a day after I started it. I’ve had my safety and ship protocol briefing, and we are underway. We’ve passed the barrier islands, and the ship is starting to rock a bit. Here we go! We have another 5 hours or so to go to get to our first sampling station, so the science work will start tonight. One final photo – to get out of the tight spot we were docked in, a tugboat was necessary:

 Word of the Day (time to start learning the terminology):

Neuston – the organisms that are found on the very top of the water, in the surface film. Contrast that with plankton, which can be said to be found within the water, not always right at the surface.
