Science and Technology Log
What is science technology? One simple definition can be ‘tools to help humans do science’. We have talked about some of the tools used aboard the Oregon II, like FSCS and CTD, but what are some other tools used that are not high tech?
Believe it or not, a shovel is an important tool on the ground fish survey. When a catch comes in, the net hovers over empty baskets and the catch is slowly released to fill the baskets. Once all of the catch has been emptied from the net, shovels are used to pick up the rest of the catch from the deck that fell out during emptying. In the wet lab we use scrappers to move the catch along the tray where we sort the organisms. When it comes to identification paperback field guides and laminated posters can help with ID.
So what do we do with the organisms we collect data on and identify?
It was mentioned that the SEAMAP survey collects data for many different agencies, but during the data collection we also save specimens for scientist from universities and other research groups. If a scientist is doing research on a particular species of batfish for example, once we collect data on the batfish we print a label for that scientist, bag the fish in zip loc baggies, and then put the specimens in the freezer below deck.
Station board – stations with a star beside them are NSIL stations. Stations with a “B” are stations where we drop the bongo nets (mentioned in an earlier log).
For commercial seafood we bag specimens to go to NSIL (National Seafood Inspection Lab). Not every station we drop the nets for is a NSIL station, but when we do have a NSIL station we follow a similar sample saving protocol to the one used for research scientists. These samples get labeled, placed in zip-loc baggies, and then they’re sent on to the freezer. However, because of the Deep Water Horizon oil spill in the gulf, the way we saved some of the samples for NSIL was different, because these samples are going to be sensory tested. In other words ‘sniff’ tested. For this test, the specimens had to be wrapped in foil to help contain any scents so that the ‘sniff testers’ (people trained to pick up petroleum scent at an amazing 100 ppm) can identify if petroleum products are present. For leg II the focus is on chemical sampling for petroleum. However, protocols can change daily when you are sampling during a disaster.

A few days ago our new protocol called for storing NSIL samples first to ensure we have enough freezer space, then other requesters samples may be saved if time permits.
Here is a CNN video clip about seafood safety.
We have a long list of the scientific names of seafood that need to be collected for NSIL but here is a list of more popular common names of seafood that you may recognize.
Some Common Commercial seafood for the Gulf Region for our groundfish survey 5-60 fathoms: Brown, White, and Pink Shrimp, Red Snapper, Gray triggerfish, crevalle jack, sand seatrout, silver seatrout, yellowedge grouper, snowy grouper, lane snapper, butterfish, wenchman, cobia, vermillion snapper, amberjack, shoal flounder, dusky flounder, and swimming crab.

Well the seas have been calm which is allowing me to get in a good 8-9 hrs of sleep each day. That is much better than the rockin' and rollin' I had been experiencing in bed. It is hard to sleep when you are sliding a few inches from head to foot of the bed, and side to side. It also creates an uneasy stomach as all of your stomach contents get mixed around.
Yesterday was a beautiful day as we could see for 10 miles (as mentioned above). One thing about night shift is that we only have 5 hours of daylight. This can be good or bad. Good part is that we have a cooler working environment and I don't need as much sunscreen. (But believe me we still get stinky from all of the shrimp and fish juice!). The bad part about night shift is we can't see into the sea as well. So 12 hours of collecting organisms we probably miss a lot of the other interesting things that are swimming near our boat when we haul up a catch.
4 days of fishing to go, then we will be cleaning the lab and heading to Mississippi.
