Science and Technology Log
An often paraphrased quote by Robert Burns goes, โThe best laid plans of mice and men often go awry.โ Well, maybe that phrase also applies to fish.
The original plans for this leg of the survey were to head out to sea on August 8th. However, a winch on NOAA Ship Bell M. Shimada stopped working before we took off. The winch is important as it helps to bring in the net which we need to catch the fish. It was a two day repair.
Then on the 10th we were all aboard and ready to leave when the wind decided to kick up. It was coming in at such an angle and strength that we did not have enough power to push away from the dock safely. So, we stayed in port for another night. We made the most of it by walking to the Oregon Coast Aquarium. It was amazing to be with the scientists as we walked through the exhibits. They have so much knowledge and experience working with the creatures on display.
Thankfully, the next day, the wind cooperated, and right around 14:50 on August 11th, we were able to set off. There were cheers and fist pumps as we began our journey.
In our mission we are taking a survey of the West Coast Pelagics, but specifically we are looking for five main fish: Pacific sardine, jack mackerel, northern anchovy, Pacific mackerel, and Pacific hake. I will be focusing on CPS, Coastal Pelagic Species, which are the sardines, anchovies, and both mackerels. Those will be caught during the night time shift that I will be working, midnight to noon. The reason we catch them at night is that during the day they are spread out and feeding, but at night they come back together for safety.
This is important work because with the data we collect we will know more about the population, size, and location of the populations and that provides guidance on what should be done for commercial fishing of those populations. One way we are able to be more efficient in catching the fish is by using certain tools to help us know where the fish are. We use acoustics technology to determine where, how many, and what kind of fish.
Today I helped get a TDR, Temperature Depth Recorder, ready to attach to the net. This sends information back to the ship about the depth of the net and the temperature of the water. The information when combined with what we know from the acoustics helps us catch what we are after.
Personal Log
Once again following the theme of the day, adaptation has been key. I knew my schedule going into this adventure was going to require me to change my sleep schedule. Once the departure date was thrown back three days, there was also no way for me to keep the midnight to noon schedule. So, I am back today trying to adjust.
I am also trying to adapt to the motion of the sea. I brought sea sickness medicine and have been taking it regularly as prescribed, but I am still feeling the effects of the motion a little bit. One good trick has been getting outside and looking at the horizon. That has helped quite a bit. I also enjoy being in the wet lab. It is a bigger space and that is helping me fight back the queasy feeling.
The food onboard has been terrific. I am eating well. Our main stewardโs name is Phil. He makes some amazing food. That is one thing I have not had to adjust to in any way.
I have the internet and am able to make Wi-Fi calls. Back home there was a flash flood. A lot of friends and family are dealing with the loss of their things. Thankfully, I have not heard any reports of people having been hurt. It is tough to be away from friends and family. Thankfully, everyone on board has been really nice. It makes a tough situation easier when you have friends to talk with. I am looking forward to not feeling sea sick soon and having amazing learning experiences in the days and weeks ahead.
Did You Know?
Greenwich Mean Time is the local time at the Royal Observatory in Greenwhich, England where the Prime Meridian was established in 1884. It is used as a reference point for telling time all around the world. On the ship it can be difficult to keep track of time. The GMT is a way for all of us who come from different time zones and are on different schedules to keep track of what time things are happening.
Can you identify this species?

Northern Anchovy – The rounded “nose” and the muppet style face are easy identifiers.
