Ship Request

STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning ( Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

Project Title: Phytoplankton patchiness and productivity: implications for our understanding of marine food web function and anticipated changes in a changing ocean Project Status: Submitted

Summary of Field Work: In this project, we propose to use ship time on the R/V Endeavor to test hypotheses about the importance of phytoplankton distribution to zooplankton predation and overall primary productivity, particularly in light of temperature, a major climate change variable.
Phytoplankton are responsible for > 50% of total, annual primary productivity and predation by heterotrophic protists (i.e. microzooplankton) remove on average 65% of this productivity (Calbet & Landry 2004). As we have recently shown in the north east Pacific, patchy phytoplankton distributions are preyed upon at 2-3-fold higher rates than equally abundant but homogeneously distributed phytoplankton (Menden-Deuer & Fredrickson, 2010). Primary productions rates are similarly enhanced within phytoplankton patches (Menden-Deuer 2012). Patch focused grazing alters, immediately the net growth of phytoplankton and ultimately the structure and productivity of marine food webs. The abundance, distribution and production of phytoplankton are projected to change as a function of increasing ocean temperatures. The request for ship time made here aims to quantify the effects of temperature and distribution on food web structure, function and primary production in the highly productive waters of coastal NE waters and Georges Bank.
We propose a cruise covering a transect from Narragansett Bay out to the productive Georges Bank area. Stations are targeted to examine differences between phytoplankton distributions and grazing rates along a transect, including near coastal and further offshore areas (Figure 1). The targeted area encompasses an environmental gradient from highly productive estuarine and coastal waters to deeper shelf waters and back onto the productive Georges Bank, that will help reveal the importance of environmental context for the rate measurements proposed. The research proposed will address important questions regarding the role of temperature in driving primary and export production of plankton and what might be anticipated with respect to changing temperature regimes in the global ocean. These data will be instrumental in seeking funding from federal research agencies, as well as contributing to training students and understanding local RI waters.
