Technical Reports

The goal of this project was to develop a clearer understanding of the role that the Gulf Stream system plays in larval fish survival and recruitment in Florida waters. The specific objectives of this study were to:

1. Determine whether the biomass of fish larva, other zooplankton, microzooplankton and phytoplankton is higher at the shoreward front of the Gulf Stream than on either side of it.
2. Characterize the assemblages of fish larvae predators and prey both at the front and on either side of it.
3. Determine if the composition, abundance and size frequency distribution of larval and juvenile fishes in the …

Carbonate Deposits In Marine Fish Intestines: A New Source Of Biomineralization, Patrick J. Walsh, Patricia Blackwelder, Kenneth A. Gill, Eva Danulat, Thomas P. Mommsen

Marine & Environmental Sciences Faculty Articles

Marine teleostean fish are hypo-osmotic to seawater. As part of a multiorgan osmoregulatory strategy they drink seawater and selectively absorb water and minerals across the intestinal epithelium. Notably, divalent cations (Ca²⁺ and Mg^2-) are left behind. We report here that in the gulf toadfish, Opsanus beta, the ionic by-products of osmoregulation in the intestine contribute to de novo formation of a carbonate mineral, tentatively identified as calcian kutnohorite. Our data suggest that intestinal mineralization is a general feature of osmoregulation in marine teleosts and that this process is an unrecognized and possibly substantial source of marine …

The Role Of Inositol Phosphate Cascade In Visual Excitation Of Invertebrate Microvillar Photoreceptors, Tamara M. Frank, A. Fein

Marine & Environmental Sciences Faculty Articles

The identity of the transmitter(s) involved in visual transduction in invertebrate microvillar photoreceptors remains unresolved. In this study, the role of inositol 1,4,5-trisphosphate (IP₃) was examined in Limulus ventral photoreceptors by studying the effects on the light response of heparin and neomycin, agents that inhibit the production or action of IP₃. Both heparin and neomycin reduce responses to brief flashes of light and the transient component of responses to steps of light, and also inhibit IP₃-induced calcium release, indicating that IP₃ plays a direct role in invertebrate visual excitation. The effects of BAPTA, …

Two New Species Of Netamelita From The Caribbean Sea (Crustacea: Amphipoda: Gammaridea), James Darwin Thomas, J. L. Barnard

Marine & Environmental Sciences Faculty Articles

The previously described species of Netamelita from California and the Gulf of Mexico are reviewed and two new species, N. brocha and N. tabaci, are described from the Florida Keys and Belize, respectively. A key to the species of Netamelita is provided. In the Caribbean Sea these species live on fine coralgal muds in forereef environments at depths of 30-40 m in a distinctive amphipod assemblage dominated by the genera Garosyrrhoe and Metaceradocus. The two new species of Netamelita were observed to plough through fine surficial flocculent materials, head downward, with urosomal appendages elevated above the sediment surface.

The Diet And Feeding Habits Of The Southern Stingray, Dasyatis Americana, In Tropical Shallow Marine Habitats, David S. Gilliam

HCNSO Student Theses and Dissertations

The diet and feeding habits of the southern stingray, Dasyatis americana, were investigated through aerial surveys, land-based observations, and quantitative analysis of stomach contents. The field research was conducted in the Exuma Cays Land and Sea Park, central Bahamas. Systematic aerial surveys and the land-based observations were made to determine population density and feeding periodicity in terms of time or tidal phase. In August, 1989, systematic surveys were flown over two cays in the Park; a 12 km² area around Waderick Wells Cay and a 21km² area around Shroud Cay. Both survey areas were flown three times …

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, C_u = (U_*/ΔU_s)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

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 …
