Compositional And Taphonomic Variations In Modern Crinoid-Rich Sediments From The Deep-Water Margin Of A Carbonate Bank, Ghislaine Llewellyn, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

Multivariate analyses of the coarse-grained fraction (>2 mm) of sediments accumulating in deep water (419-434 m) along the western margin of the Little Bahama Bank reveal identifiable, small-scale compositional and taphonomic variations among local subhabitats (ridge crest, slope, foreslope, base of slope, pavements and scour pit) separated by meters to tens of meters. Bulk composition varies between planktic-(crest and slope) and lithic-dominated (pavements, scour pit) sediments. Local macrobenthic skeletal components also vary significantly among subhabitats, but are commonly dominated by echinoid and crinoid material; crinoid columnals contribute 9-52% of the coarse skeletal component of 17 sediment samples considered. Distributional …

Port Everglades Macroinvertebrate Monitoring: Monitoring Of Benthic Macroinvertebrate Assemblages At The Southport Turning Basin And Adjacent Areas Of John U. Lloyd State Recreation Area: January 1993: Final Version, Charles G. Messing, Richard E. Dodge

Marine & Environmental Sciences Faculty Reports

This report documents the January 1993 monitoring of benthic macroinvertebrate assemblages in the Port Everglades Southport turning basin vicinity and adjacent areas of John U. Lloyd State Recreation Area. This is the fourth monitoring effort of the series carried out by Nova University Oceanographic Center. Sampling was carried out during 4-15 January and 1-22 February 1993, the extended period due chiefly to weather and tidal constraints. Comparison with results of preceding survey efforts will be included in the annual report following the August 1993 survey. The section treating the Ponar grab samples is now complete: identifications of the remaining groups …

Second Post-Construction Report: 1992 Biological Monitoring Of The Hollywood-Hallandale Beach Renourishment. Draft, Richard E. Dodge, Walter Goldberg, Steven C. Hess, Charles G. Messing

Marine & Environmental Sciences Faculty Reports

In 1990. Nova University (Contractor) with Coral Reef Associates and ERM South (Subcontractors) was awarded a contract to provide biological monitoring services for the Hollywood Hallandale Beach Renourishment Project. A notice to proceed for the initial biological monitoring (Pre-construction) was issued in September. 1990. Pre-construction field monitoring took place in October. 1990. Renourishment dredging began in April and ended August, 1991. Approximately 1.2 million cubic yards of sediment were removed and subsequently emplaced on 5 miles of shoreline. The first post-construction monitoring took place in October. 1991. On August 24.1992 the eye of Hurricane Andrew passed some 30 miles to …

Port Everglades Macroinvertebrate Monitoring: Monitoring Of Benthic Macroinvertebrate Assemblages At The Southport Turning Basin And Adjacent Areas Of John U. Lloyd State Recreation Area: August 1992 (With A Summary Of The August 1991 And January 1992 Surveys), Charles G. Messing, Richard E. Dodge

Marine & Environmental Sciences Faculty Reports

This report documents the August 1992 monitoring of benthic macroinvertebrate assemblages in the Pon Everglades Southpon turning basin vicinity and adjacent areas of John U. Lloyd State Recreation Area. This is the third monitoring effort of the series carried out by Nova University Oceanographic Center. Sampling was carried out chiefly during the first two weeks of August 1992. Hurricane Andrew and its aftermath resulted in delays in sampling at several sites and in analyzing data. A two-week postponement in submission deadline was requested and granted. An additional postponement, to 31 January 1992, was requested due to a move at the …

Skeletal Structural Basis Of Density Banding In The Reef Coral Montastrea Annularis, Richard E. Dodge, Alina Szmant-Froelich, R. Garcia, Peter K. Swart, A. Forester, J. J. Leder

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Density banding in coral skeletons can provide for reconstruction of the coral's growth en- vironment over long periods. The physical differ- ences between low and high density portions of a skeletal band are not well understood. The skeletal architecture of M. annularis from Southeast Flor- ida, the Florida Keys, St. Croix, the Bahamas, and Mexico was compared in X-ray revealed high den- sity (HD), low density (LD), and stress HD bands. Density changes arose from differences in the size, but not spacing, of exothecal structural elements (horizontal dissepiments and vertical costae). En- dothecal architecture size (e.g., columella, dissepi- ments, septa) …

A Survey Of The Stony Coral Community Composition Of Pompano Ledge, Broward County, Florida, With A Preliminary Evaluation Of The Effectiveness Of Mooring Buoys In Reducing Coral Damage, John D. Hocevar

HCNSO Student Theses and Dissertations

Stony corals of Pompano Ledge, First Reef, Broward County, Florida were sampled in situ using a new reef assessment method. The circular-radial method was used to assess the effectiveness of mooring buoys in reducing damage to reefs. Data will be part of a long-term monitoring study of·buoy impacts. The parameter of recent injury was used to provide preliminary information on buoy effectiveness.

Results were as follows: approximately 6% of the study area was covered by stony corals, with an average of 3 colonies per square meter. Diversity based on abundance (H'n) was 1 .7, and diversity based on relative coverage …

Microzooplankton Distributions In The Irish Sea, Carol A. Burkart

HCNSO Student Theses and Dissertations

The purpose of this study was to determine the distributions and abundances of microzooplankton across a front in the Irish Sea, and to test the hypothesis that the structure which develops within the microzooplankton community is the result of the interactions within the communities.

Eight sites were sampled on May 1-2, 1989 along a transect from Liverpool Bay, England to Dundalk Bay, Ireland. The transect crossed both the Liverpool Bay and western Irish Sea fronts; sites were positioned with respect to water type (e.g., coastal, thermally mixed, thermally stratified) . Five sites were sampled by double Longhurst-Hardy Plankton Recorder (LHPR) …
