Welcome to the web site for Sediment and Solute Transport on Rivers and Margins (SSTORM) Research Group! Reide Corbett and J.P. Walsh from East Carolina University and the UNC Coastal Studies Institute lead the team.
Check out our research in/on wetlands, estuaries, barrier islands, shelves and groundwater.

Sunrise, Nutrients and a Treadmill
above are from 3:15 a.m. As the sun starts to come up it creates the
most amazing colors against the blues and whites of the icebergs. This
morning is very brisk with the air temperature at -1C and the wind chill
at –6C. We still have really amazing weather with minimal seas and
wind. These conditions have helped us get ahead of schedule for our
One of the samples that we take with every CTD cast is for nutrients.
Nutrients are fundamental requirements primary producers use to assemble
cell material. They are important sources of fuel for the basis of the
food chain. To sample for nutrients we collect a small water sample
from the CTD Rosette while wearing gloves and a clean tube in an effort
to keep the sample as pure as possible. The sample is collected in 60mL
syringes and pumped through a filter that will catch any sediment or
large organisms. The filtered water is stored in a 60mL bottle and
placed in a -80C freezer. The analysis of nutrients will not take
place on the ship, and the samples will be shipped back to the United
States where they can be processed in a lab with the proper equipment.
As part of this research we hope to better understand what nutrients are
available in the coastal waters off of the Western Antarctic Peninsula,
and how those waters move.
In our Smith Mac grab sample we had some interesting animals again. We
are working to find out what they are exactly, but one looks a lot like
a heart urchin and the other some type of worm. They were found over
400 meters down.
Before my science shift last night I had the unique experience of
running on a treadmill while the ship was underway. The rolling of the
ship added a bit of challenge to what I normally find as a somewhat
boring task, and the view of icebergs passing by while running also
helped keep it interesting. We should be headed into Palmer Station
tomorrow, and I am ready to set foot on the Antarctic Continent.
