Microzooplankton Grazing And Productivity In The Central And Southern Sector Of The Indian River Lagoon, Florida, Jennifer Putland, Tracey Sutton
Microzooplankton Grazing And Productivity In The Central And Southern Sector Of The Indian River Lagoon, Florida, Jennifer Putland, Tracey Sutton
Marine & Environmental Sciences Faculty Articles
Microzooplankton grazing was measured with the dilution method in the central and southern sectors of the Indian River Lagoon during summer 2006 and 2007. Microzooplankton actively grazed phytoplankton during all experiments. Grazing rates averaged (± SD) 0.956 ± 0.19 d-1 and ranged from 0.54 to 1.36 d-1. Phytoplankton carbon, measured by microscopy, averaged 314 ± 251 μg C L-1 and ranged from 115 to 936 μg C L-1. Microzooplankton ingestion rates averaged 303 ± 260 μg C L-1d-1 and ranged from 90 to 907 μg C L-1d-1. …

Stable oxygen isotope ratios (δ18O) of coral skeletons are influenced by ambient water temperature and by the oxygen isotope ratio in the surrounding sea water, which, in turn, is linked to evaporation (salinity) and precipitation. To investigate this relationship more thoroughly, we collected hourly temperature data from the Hen and Chickens Reef in the Florida Keys between 1975 and 1988 and compared them to the δ18O of Montastraea annularis skeleton that grew during the same interval. To ensure that we obtained the correct oxygen isotopic range in the skeleton we typically sampled the coral at a …
