Caitlin departed on the R/V Weatherbird II last weekend to collect samples from, and redeploy, sediment traps in the Gulf of America. She will be joined by a group of Eckerd College students for their first research cruise experience.

Paleoceanographic Proxy Calibration
A sediment trap time series in the northern Gulf of America is used to better assess the control of environmental variables (e.g., temperature and salinity) on the flux of both microfossils and molecular fossils to the sediments. The information gained from sediment trap studies is used to develop better proxy-based estimates of past oceanographic conditions from analyses of microfossils and...
Globigerinoides ruber Sediment Trap Data in the Gulf of Mexico
We present results here from a high-resolution (1-2 weeks) and long-running sediment trap time series from the northern Gulf of Mexico which allows for a detailed assessment of the seasonal distribution, size, morphological variability and geochemistry of co-occurring pink and white chromotypes of Globigerinoides ruber. The flux of both chromotypes is highly correlated, and both...
Globorotalia truncatulinoides Sediment Trap Data in the Gulf of Mexico
Modern observations of planktic foraminifera from sediment trap studies help to constrain the regional ecology of paleoceanographically valuable species. Results from a weekly-resolved sediment trap time series (2008-2014) in the northern Gulf of Mexico demonstrate that 92% of Globorotalia truncatulinoides flux occurs in winter (January, February, and March), and that encrusted and non...
Seasonal flux and assemblage composition of planktic foraminifera from the northern Gulf of Mexico, 2008–14
The U.S. Geological Survey anchored a sediment trap in the northern Gulf of Mexico in January 2008 to collect seasonal time-series data on the flux and assemblage composition of live planktic foraminifers. This report provides an update of the previous time-series data to include continuous results from January 2013 through May 2014. Ten taxa constituted ~95 percent of both the 2013 and...

Lunar periodicity in the shell flux of planktonic foraminifera in the Gulf of Mexico
Synchronised reproduction offers clear benefits to planktonic foraminifera – an important group of marine calcifiers – as it increases the chances of successful gamete fusion. Such synchrony requires tuning to an internal or external clock. Evidence exists for lunar reproductive cycles in some species, but its recognition in shell flux time series has proven difficult, raising questions...

Seasonal flux and assemblage composition of planktic foraminifera from the northern Gulf of Mexico, 2008-2012
The U.S. Geological Survey anchored a sediment trap in the northern Gulf of Mexico beginning in 2008 to collect seasonal time-series data on the flux and assemblage composition of live planktic foraminifers. This report provides an update of the previous time-series data to include results from 2012. Ten species, or varieties, constituted ~92 percent of the 2012 assemblage...
