Cruise update 7/23/13

Made it through the C and D’ transects last night. Started on D this morning when the day shift came on. I’m on the 7am-7pm shift, which is nice. Crew had to re-tap our CTD and then re-spool an entire winch, at sea, yesterday. Unbelievably hard work. Good on ’em. The sea state has stayed mellow, and we’ve got nice sun today. Full moon last night was a sight. So are all the platforms everywhere. Sampling in the Gulf is a trip because of the ubiquitous oil platforms in our general area. Some of our stations are right next to them. And Nancy’s group even has real-time oxygen sensors mounted on a few at depth.


Every one of those little black dots on the bottom half of the screen is an oil platform.


Cruise update 7/22/13

We cruised through the night to the mouth of the Mississippi River, where we went up the southwest pass for a bit yesterday. The point was to get a salinity/nutrient profile so that we can accurately judge which phenomena we see in on the shelf are biological vs. due to dilution effects from the river plume. Then we proceeded to the A’ and A transects, which we finished during the night. Starting the B transect this morning. I’m on the 7am-7pm shift, which is nice. Sea state is very mellow. Overcast the last couple days with scattered showers, 2-4 ft swell. The Pelican is a nice ship. Good stability, good food! Not great internet. Check out the official shelf wide cruise blog, which also has a map of our sampling stations. I’ll try to give updates whenever we’re close enough to land for cellular data.


Northern Gulf of Mexico shelfwide hypoxia cruise

Today I leave on my first cruise as a new faculty at LSU. I’m joining Nancy Rabalais and collaborators of hers from the Louisiana Universities Marine Consortium (LUMCON), as well as a graduate student from Olivia Mason‘s lab at Florida State University (@OUMasonLab) to participate on this year’s shelfwide hypoxia investigation in the “dead zone” of the Northern Gulf of Mexico. Nancy and her colleagues have been studying this phenomenon for almost 30 years. I’ll post updates as we go (and hopefully add to the rest of this new site).
