Densities measured with CTDs along the 4 transects on which we
collected depth stratified plankton samples with a tucker trawl from
August 9-12, 2010.
Positions of the tucker trawls on NYHOPs forecast
temperatures on August 11, 2010 showing the cool water
off the mouth of the estuary. This transect is also shown
stretching southwest to northeast in the plot above.
RUCOOL used our CTD data to decide how to ballast a robot glider launched today off Sandy Hook. The glider is to fly from Sandy Hook south to Cape May, New Jersey in a zigzag pattern from the near shore to 40 km offshore. The glider will provide Steven's institute with temperature and salinity data to better tune the NYHOPs model for near shore forecasting. It is also equipped with a dissolved oxygen and other optical sensors that will be used in the State of New Jersey's water quality monitoring program. This is exactly the kind of model tuning and habitat condition data we need to do our seascape work better.
At the last minute RUCOOL asked us if we could help with a vessel to launch the glider. This was invitation for real fun. Below are some pictures of the robot glider launch and a pod of porpoises that we saw on the way home. The mission of glider RU-16 over the next few weeks can be followed here.
