Biological And Physical Analysis Of Currents And Water Masses Off The Coast Of Southeast Florida, Stephanie Healey
HCNSO Student Theses and Dissertations
Biological and physical sampling of a 10km long, east-west transect was performed during 2007, off the coast of southeast Florida. Temperature and salinity measurements were recorded using a conductivity-temperature-depth (CTD) sensor, and current direction and magnitude measurements were recorded using an acoustic Doppler current profiler (ADCP). Zooplankton samples were collected, during the daytime, using a Tucker multiple net mid-water trawl, with 760μm mesh, at intended depths of ~25m and ~200m, at three stations along the transect. Laboratory analysis indicated that several currents and water masses influenced the density distribution of calanoid copepods and chaetognaths. During April and September 2007, a …

Copepods, minute crustaceans, are vital constituents of marine food web dynamics in tropical ecosystems. Ecologically, copepods provide the link between primary production and tertiary consumers. Changes in population structure and densities may impact ecosystem stability and production on small to large spatial scales. The present study examined the influence of the Florida Current on copepod population densities off the coast of Fort Lauderdale, Florida due to limited data in the area. Samples were collected during February and July 2007 at two locations, Stations A and B. Station A, dependent on current dynamics, fluctuated between the most western boundary and the …
