What is a research cruise really?

 

Mesoscale Survey

A research "cruise" is far from a tourist vacation, but rather, a scientific endevour to collect data and test hypotheses for various research questions. Between May 1-21, 2003 the Research Vessel (R/V) Wecoma conducted a mesoscale survey in the Gulf of Alaska. During this cruise, scientists used a variety of instruments to collect data on water temperature, salinity, current velocity, chlorophyll concentration, and other physical oceanographic measurements.

The science, people, and scenery on the mesoscale survey more than made up for the lack of a luxurious "cruise" atmosphere. Above, the SeaSoar is seen resting on deck and being launched off the back of the Wecoma--all from a beautiful location in the Gulf of Alaska.

More cruises!

From July 21 to August 12,the R/V Wecoma conducted another mesoscale survey in the Gulf of Alaska. Three other cruises coincided with this cruise to better utilize real time data collected at sea. To learn about the other research vessels and their projects, go to one of the following:

Alpha Helix: Owned by NSF, but operated by the Institute of Marine Sciences at the University of Alaska, the Alpha Helix conducted a NEP process study in the Gulf of Alaska from July 20 to August 12.

Miller Freeman: Owned by the National Oceanic and Atmospheric Administration (NOAA) and operated by the Pacific Marine Center, the Miller Freeman did fish tows in Prince William Sound between July 18 and August 9.

Pandalus: The Pandalus conducted fish tows between August 2–9 to aid in understanding how the Northern Gulf of Alaska marine ecosystem responds to climate variability.
