Helium isotope variations in peridotite, gabbro and basalt from the Kane Oceanic Core Complex

Creator:: Konrad, Kevin
Abstract:: The Kane Oceanic Core Complex (OCC) is a valuable window into crustal architecture and chemical composition of the lithosphere beneath a slow-spreading ocean ridge. A suite of > 30 samples (comprised of whole rocks, mineral separates and basalt glasses) has been analyzed for ³He/⁴He isotope ratios and He concentrations. Gas...

Holocene sediments of the South Atlantic Ocean : the calcite compensation depth and concentrations of calcite, opal and quartz

Creator:: Ellis, David Burl
Abstract:: The concentrations of calcite, opal and quartz have been measured in 113 South Atlantic core tops. The remainder of the total sample has been calculated as clay. A method for the quantitative determination of opal has been developed. Calcite is the dominant factor in South Atlantic sediments; its pattern can...

Decomposition of absorption coefficients and decorrelation lengthscales of hydrographic and inherent optical properties in the Middle Atlantic Bight

Creator:: Simeon, Jennifer J.
Abstract:: This investigation is an exploration of the use of inherent optical properties towards further elucidation of coastal circulation processes occurring on the continental shelf and slope in the Middle Atlantic Bight, south of Cape Cod Massachusetts, during 14-Aug to 1-Sep 1996 and 25-Apr to 15-May 1997. Assessing the possibility of...

Analysis of meteorological observations from an array of buoys during JASIN

Creator:: Ishida, Hiroshi
Abstract:: Observations of wind speed and direction, air and sea temperature, and solar radiation were obtained from an array of buoys in JASIN. The observations were analyzed to show spatial and temporal variability. Spectra of wind speed and air and sea temperature were computed to illustrate the distribution of variance over...

Movement patterns and marine habitat associations of juvenile loggerhead sea turtles (Caretta caretta) in the southwestern Atlantic Ocean

Creator:: Barceló, Caren
Abstract:: Bycatch, or the incidental capture of non-target species, has been implicated as one of the main factors leading to population declines of many large marine vertebrates, including sea turtles. To effectively manage and conserve these long-lived species, their marine distribution, high use areas, foraging habitats, and regions of highest likelihood...

Defining habitat preferences of pelagic loggerhead sea turtles (Caretta caretta) in the North Atlantic through analysis of behavior and bycatch

Creator:: McCarthy, Abigail L.
Abstract:: For many species of marine turtle the characteristics that define pelagic habitat have yet to be fully identified. A better understanding of these habitat characteristics is critical to reduce high seas fisheries interactions with turtles, especially as the status of many turtle populations has placed them on the threatened or...

Transport of the copepod, Calanus finmarchicus, in the northwest Atlantic during diapause

Creator:: Kowalke, Gregory L.
Abstract:: The copepod Calanus finmarchicus is the most important and biomass dominant mesozooplankter in the temperate-boreal North Atlantic. C. finmarchicus has an overwintering phase, termed diapause, during which it descends to great depths (300-2000m) and is metabolically quiescent for up to ten months. Changes in the currents at depth due to...

Satellite monitored dive characteristics of the northern right whale, Eubalaena glacialis

Creator:: Nieukirk, Sharon L.
Abstract:: The western North Atlantic population of the northern right whale (Eubalaena glacialis) was severely depleted by whaling over the last century. Despite over fifty years of protection, fewer than four hundred individuals are believed to exist in the North Atlantic. Relatively little is known about the diving behavior, respiratory physiology,...

Evaluation of length distributions and growth variance to improve assessment of the loggerhead sea turtle, (Caretta caretta)

Creator:: Vaughan, Jason R.
Abstract:: Nest counts from the largest subpopulation of the loggerhead sea turtle (Caretta caretta) in the Atlantic, peninsular Florida, have been declining since 1998. Analyzing trends of nests and adult females is insufficient to determine the overall status of a sea turtle population, due to variation in nesting frequency and a...

Relationship between tropical Atlantic Sea surface temperature variability and southern Indian Ocean tropical cyclones

Creator:: DeBlander, Evan F.
Abstract:: Recent studies have found that equatorial Atlantic sea surface temperature (SST) variability may be influencing tropical Indian Ocean climate (Kucharski 2009, Wang 2009). Due to the economic and social impact of tropical cyclones, it is important to investigate how an Atlantic-Indian Ocean connection may be affecting tropical cyclone behavior in...
