This year's voyage is the first of two annual research surveys in the Gulf of Mexico for the NOAA RESTORE Act Science Program. Our project, "Research, observation, and monitoring to support long-term sustainability in the GoM ecosystem, including fish stocks, fish habitat, and fishing industries," is in collaboration with some new partners to the FORCES Lab. Read on and get introduced to the project's PI from Florida State University, Mike Stukel!

My name is Mike Stukel, and I am an assistant professor at Florida State University. I am a plankton ecologist and biogeochemist in the FSU Plankton Ecology and Biochemistry Lab. I study
the role that
some of the smallest organisms in the ocean play in the global
carbon cycle and
their role in removing carbon dioxide from the atmosphere. On this cruise, I am studying
the role that
different nutrients play in limiting the primary production of
phytoplankton. These tiny algae are
responsible for half of the world’s photosynthesis and half of the
oxygen that
you breathe. Their
photosynthesis also
supports the entire marine ecosystem of the open ocean Gulf of
Mexico. One of my goals in
this project is to
quantify the food web pathways that partition this phytoplankton
production
between either the biological pump (which transports atmospheric
CO2 into the
deep ocean where it can be stored for centuries) or higher trophic
levels
including larval tuna.

My goal for this cruise is to understand the base of the food web that supports larval tuna. In particular, I am interested in whether the algae responsible for photosynthesis are ultimately getting their nutrients from upwelling that brings nutrient-rich deep water into the sunlit surface zone or whether special phytoplankton (called Nitrogen-fixers) are creating their own nutrients from the nitrogen gas that is abundant in the atmosphere and ocean. Answering this question is important to understanding whether or not total productivity in the Gulf of Mexico will decrease due to climate change.
