Time period of temporary agreement: Dates (month/day/year): 10/29/2003 - 12/09/2003 SeaWiFS HRPT Station to provide data: HNBP (R/V Nathaniel B. Palmer) List of Authorized Users to access real-time data. 1. Patrick Neale Project Title: Mixing and UV Radiation in the Ross Sea (MIXURS) Principal Investigator(s): Patrick Neale, Wade Jeffrey, Ann Gargett Funding Agency(s): NSF - Polar Programs Description of the Research Project and Justification for Real-time SeaWiFS Data: Support is requested for the project "Mixing and UV radiation in the Ross Sea" (MIXURS), P.I.s Neale, Jeffrey and Gargett, and associated projects on UV effects on nitrogen metabolism in Phaeocystis (P.I. Goes) and on DMS cycling in the Ross Sea, (P.I.s Kleber and Kiene). All these groups will be performing studies on the cruise NBP03-05A, October 26 to December 13, 2003. The principal objective is to understand the effects of UV radiation on communities of the colonial phytoplankten, Phaeocystis antarctica, and associated communities. UV effects will be defined on photosynthesis, nitrogen and sulfur metabolism of Phaeocystis and bacterioplankton, and assessments will take into account vertical-mixing as a determinant of exposure to near surface irradiance. The Real-time SeaWiFS data access will aid the research by guiding the siting of stations in the Ross Sea Polynya. Since Phaeocystis dominates the phytoplankton community in the polynya at this time of year, areas of higher Chl in the SeaWiFS images are likely to be locations of P. antarctica blooms.
