Several specimens of the isocrinid crinoid Neocrinus decorus were collected from a depth of 420 m off Bahamas Islands with the research submersible Johnson Sea Link. To study growth rates, these specimens were tagged, deployed and then recovered 250 days later. The average growth rate of stalk length is 10.8 cm.year−1 with a maximum value at 14.3 cm.year−1. These results allow us to propose a model of growth and regeneration for stalked crinoids in which the energy allocation is modulated through time to the arms and the stalk. Following arm autotomy, in order to re-establish optimum filtration …

Oligotrophic tropical-subtropical oceanic regimes constitute the largest and most ancient ecosystem on earth, with these enormous areas being characterized by high faunal diversity. The stability and age of the ecosystem have enabled the evolution of many similar species niches where there is considerable overlap in niche parameters such as food and space, resulting in high species packing, especially in the epi- and mesopelagic zones. Competition for limited resources undoubtedly exists and has been described by MacArthur (1972; Geographical ecology, Harper and Row, New York) as diffuse competition where each species is impacted by many other species sharing the environment. Most …

High-resolution probes mounted on the bow of the vessel at a 1.7-m depth in an undisturbed region ahead of the moving vessel were used for microstructure and turbulence measurements in the near-surface layer of the ocean during TOGA COARE. The probes measured temperature, conductivity, pressure, three-component fluctuation velocity, and two components of acceleration. Accumulation of large amounts of high-quality nearsurface data poses a difficult challenge, and deployment from the bow of a ship, such as is done with these sensors, requires rugged, well-calibrated, and low-noise sensors. The heaving motion of the ship that causes the sensors to break through the …

The United States submarine Memphis grounded in approximately 10 m water depth on a tropical coral reef ofT southeast Florida in February, 1993. The grounding caused extensive physical and biological damage to the reef substrate and to the coral community. As part of a claim by the State of Florida against the United States, the impact of the grounding was assessed, and the area of damage was determined through field and photographic studies. A recovery rate for the reef was assigned from literature estimates. The NOAA Habitat Equivalency Model (HEM) was used to calculate the reef area needed to be …
