Biography
I earned my Bachelor of Arts Degree in Geology at The University of Akron with a certificate in Environmental Science in 2008. I am currently working on my Masters Degree at The University of South Florida College of Marine Science with a focus on Geological Oceanography.

Paleoceanographic Proxy Calibration
A sediment trap time series in the northern Gulf of Mexico 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 ...
Climate and Environmental Change in the Gulf of Mexico and Caribbean
This project documents paleoceanographic, climatic, and environmental changes in the Gulf of Mexico and adjacent land areas over the last 10,000 years. The paleoenvironmental data is used to determine rates of change in the past, and to better understand both the natural and anthropogenic factors that contribute to climate variability on inter-annual to millennial timescales.
Considerations for Globigerinoides ruber (white and pink) paleoceanography: Comprehensive insights from a long‐running sediment trap
We present a detailed analysis of the seasonal distribution, size, morphological variability and geochemistry of co‐occurring pink and white chromotypes of Globigerinoides ruberfrom a high‐resolution (1–2 weeks) and long‐running sediment trap time series in the northern Gulf of Mexico. We find no difference in the seasonal flux of the two...
Richey, Julie N.; Thirumalai, Kaustubh; Khider, Deborah; Reynolds, Caitlin E.; Partin, Judson W.; Quinn, Terrence M. Environmental controls on the geochemistry of Globorotalia truncatulinoides in the Gulf of Mexico: Implications for paleoceanographic reconstructions
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 ...

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...
Reynolds, Caitlin E.; Richey, Julie N. 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...

Weekly resolution particulate flux from a sediment trap in the northern Gulf of Mexico, 2008-2012
The U.S. Geological Survey anchored a sediment trap in the northern Gulf of Mexico to collect time-series data on sediment flux from 2008 to 2012. There are continuous measurements of total mass flux and organic carbon flux (ogC) at 7–14 day resolution from 2008 to 2012. The flux of calcium carbonate (CaCO3), particulate nitrogen (nitro), and...

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...

Seasonal flux and assemblage composition of planktic foraminifera from the northern Gulf of Mexico, 2008-11
The U.S. Geological Survey anchored a sediment trap in the northern Gulf of Mexico 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 2011. Ten species, or varieties, constituted ~92 percent of the 2011...

Seasonal flux and assemblage composition of planktic foraminifera from the northern Gulf of Mexico, 2008-2010
The U.S. Geological Survey anchored a sediment trap in the northern Gulf of Mexico 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 2010. Ten species, or varieties, of planktic foraminifers constituted ~...

Benthic habitat classification in Lignumvitae Key Basin, Florida Bay, using the U.S. Geological Survey Along-Track Reef Imaging System (ATRIS)
The Comprehensive Everglades Restoration Plan (CERP) funded in partnership between the U.S. Army Corps of Engineers, South Florida Water Management District, and other Federal, local and Tribal members has in its mandate a guideline to protect and restore freshwater flows to coastal environments to pre-1940s conditions (CERP, 1999). Historic...

Sediment trap in Gulf of Mexico recovered one last time, marking the culmination of a 12-year time series
Julie Richey, Caitlin Reynolds, and colleagues retrieved a sediment trap from the northern Gulf of Mexico during a 3-day cruise (February 7–9, 2020) on board the R/V Pelican. The trap was deployed in 1,200 m of water in 2008 and had been collecting sinking particles from the water column to be used in paleoclimate proxy-calibration studies.
