Slippery Near-Surface Layer Of The Ocean Arising Due To Daytime Solar Heating, Vladimir N. Kudryavtsev, Alexander Soloviev May 1990

Slippery Near-Surface Layer Of The Ocean Arising Due To Daytime Solar Heating, Vladimir N. Kudryavtsev, Alexander Soloviev

Marine & Environmental Sciences Faculty Articles

Measurements made in the Equatorial Atlantic during the 35th cruise of the R/V Akademic Vernadsky using a free-rising profiler and drifters revealed a near-surface slippery layer of the ocean arising due to daytime solar heating. The solar heating warms and stabilizes the surface layer of the ocean. This suppresses turbulent exchange and limits the penetration depth of the wind-induced turbulent mixing. The heated near-surface layer is then slipping over the underlying water practically without friction. At daytime warming of 1°C the resistance coefficient in the upper 5-m ocean, Cu = (U*Us)2 became …


Biozonation Of Deep-Water Lithoherms And Associated Hardgrounds In The Northeastern Straits Of Florida, Charles G. Messing, A. Conrad Neumann, Judith C. Lang Feb 1990

Biozonation Of Deep-Water Lithoherms And Associated Hardgrounds In The Northeastern Straits Of Florida, Charles G. Messing, A. Conrad Neumann, Judith C. Lang

Marine & Environmental Sciences Faculty Articles

Elongated carbonate mounds ("lithoherms") oriented parallel to prevailing northerly bottom currents at moderate depths (500-700 m) along the western margin of the Little Bahama Bank exhibit a consistent faunal zonation characterized by attached, suspension-feeding invertebrates. The four most abundant macroepibenthic groups (alcyonarians, crinoids, sponges and stylasterid hydrocorals) dominate all hard substrates examined except upcurrent ends and crests of lithoherms. We recognize three faunal zones on these mounds: a Coral Zone (Lophelia prolifera) restricted to the upcurrent end; a Zoanthid Zone (?Gerardia sp.) along upcurrent crests, and a Crinoid/Alcyonarian Zone along lithoherm flanks and downstream crests. Taxa characteristic of the latter …

Sea Turtle Conservation Program, Broward County, Fl 1990 Report, Curtis M. Burney, Catherine A. Mattison Jan 1990

Sea Turtle Conservation Program, Broward County, Fl 1990 Report, Curtis M. Burney, Catherine A. Mattison

Marine & Environmental Sciences Faculty Reports

Since 1978, the Broward County Environmental Protection Department (BCEPD) has provided for the conservation of endangered and threatened sea turtle species within its area of responsibility. Broward County is within the normal nesting areas of three species of sea turtles: the loggerhead sea turtle (Caretta caretta), the green sea turtle (Chelonia mydas) and the leatherback sea turtle (Dermochelys coriacea). The loggerhead is listed as a threatened species, while the green and leatherback are listed as endangered under the U.S. Endangered Species Act, 1973, and Chapter 370, F.S.

Since these statutes strictly forbid any disturbance …

Ensayara Jumane, A New Species From Belize, Caribbean Sea (Amphipoda, Lysianassidae), J. L. Barnard, James Darwin Thomas Jan 1990

Ensayara Jumane, A New Species From Belize, Caribbean Sea (Amphipoda, Lysianassidae), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Ensayara jumane is described from Belize. It differs from the west Mexican Ensayara ramonella J. L. Barnard (1964) in the excavate posteroventral margins of article 2 on pereopods 5-7, and the sparse (9 versus 25) setae on articles 5-6 of gnathopod I. A new diagnosis for Ensayara, a key to species, list of species, references to original descriptions and geographic codes for each species are provided. This is the first record of the genus from the Caribbean Sea.


Gitana Dominica, A New Species From The Caribbean Sea (Amphipoda: Amphilochidae), James Darwin Thomas, J. L. Barnard Jan 1990

Gitana Dominica, A New Species From The Caribbean Sea (Amphipoda: Amphilochidae), James Darwin Thomas, J. L. Barnard

Marine & Environmental Sciences Faculty Articles

The new species Gitana dominica is described from Dominica in the Lesser Antilles; it is the first record of the genus from the western Atlantic Ocean. The new species differs from its closest relative, Gitana calitemplado, from California, in the shorter and posteroventrally excavate coxa 1. Gitana is reviewed.


Aspects Of Phytoplankton Chlorophyll A Carbon-Specific Growth Rates, And The Distributions Of Chlorophyll A And Primary Productivity In Relation To Water Column Structure In The Eastern North Atlantic Ocean, Denis William Frazel Jan 1990

Aspects Of Phytoplankton Chlorophyll A Carbon-Specific Growth Rates, And The Distributions Of Chlorophyll A And Primary Productivity In Relation To Water Column Structure In The Eastern North Atlantic Ocean, Denis William Frazel

HCNSO Student Theses and Dissertations

This dissertation consists of three chapters, two of which are presented in manuscript form. Chapter One is an introduction and review of the measurement of phytoplankton chlorophyll a carbon-specific growth rates. Chapter Two consists of the manuscript ASPECTS OF CHLOROPHYLL a CARBONSPECIFIC GROWTH RATE IN THE EASTERN NORTH ATLANTIC OCEAN. It has been formatted in accordance with the specifications of the oceanographic journal Marine Ecology Progress Series. In Chapter Two, an evaluation of the short-term kinetics of the labeling time of natural phytoplankton populations in different oceanic regions showed that chI a labeling varied in relation to both environmental conditions …
