This report provides an update of the previous time-series data to include results from 2010. Ten species, or varieties, of planktic foraminifers constituted ~90 percent of the assemblage: Globigerinoides ruber (pink and white varieties), Gs. sacculifer, Globigerina calida, Globigerinella aequilateralis, Globorotalia menardii group, Gt. truncatulinoides, Pulleniatina spp., Orbulina universa, and Neogloboquadrina dutertrei. The mean daily flux was 219 tests per square meter per day (m-2 day-1), with maximum fluxes of >600 tests m-2 day-1 during late December and minimum fluxes of <40 tests m-2 day-1 during late August. Globorotalia truncatulinoides showed a clear preference for the winter, consistent with data from 2008 and 2009. Globigerinoides ruber (white variety) flux data for 2010 (average 29 tests m-2 day-1) showed a steady increase of about a factor of 3 since 2009 (average 11 tests m-2 day-1), and an almost 10-fold increase from the 2008 flux (average 3 tests m-2 day-1). The progressive increase in flux resulted in a relatively large increase in percent abundance of total assemblage from 2008 (1.5 percent) to 2010 (12. 4 percent). In addition, though Gs. ruber (white) percent abundance increased from 4.9 percent in 2009 to over 12 percent in 2010, it continued to occur in lower abundance than the 20-30 percent indicated by dead-assemblage records from nearby sediments. Purpose: A sediment trap was moored in the northern Gulf of Mexico in January 2008 as part of a U.S. Geological Survey (USGS) Mendenhall Postdoctoral Fellowship project. The trap, equipped with an automated sampling system, has continuously collected material in the water column from January 2008 to the present and is currently deployed. Information on the trap, trap mooring, planktic foraminifers as climate proxies, and the results from the first year are detailed in Tedesco and others (2009). In this paper, we update results from the sediment-trap series to include material collected between January and December of 2010. The paper presents the data without interpretation.

Logical_Consistency_Report: Foraminifera species were designated based on current species identification methods. All scientist participating in the categorization process used identical materials in order to ensure consistent classification. Completeness_Report: All data was accounted for and recorded for every sample taken. Results are representative for all findings observed within each sample. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Latitude and longitude at sampling sites were taken from Google Earth (2010). Lineage: Process_Step: Process_Description: Collected samples are counted using a hand tally counter and entered into in Microsoft Excel (2008). Species counts are reported as flux in tests per square meter per day. Flux was calculated in excel by multiplying the individual species counts by number of splits, then dividing by sampling length, which was typically 7 or 14 days.
