Sands and environmental conditions impact the abundance and persistence of the fecal indicator bacteria Enterococcus at recreational beaches
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-09)
The marine fecal indicator Enterococcus is measured at beaches to detect fecal contamination events, and beaches are closed to bathers when Enterococcus is found to exceed the federally mandated limit. This dissertation ...
Larvae from afar colonize deep-sea hydrothermal vents after a catastrophic eruption
The planktonic larval stage is a critical component of life history in marine benthic species because it confers the ability to disperse, potentially connecting remote populations and leading to colonization of new sites. ...
The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fish
Atlantic killifish populations have rapidly adapted to normally lethal levels of pollution in four urban estuaries. Through analysis of 384 whole killifish genome sequences and comparative transcriptomics in four pairs ...
Grounding-zone wedges and mega-scale glacial lineations in the Mertz Trough, East Antarctica
Glacial erosion and deposition have shaped the Mertz Trough, East Antarctica, where seafloor grounding-zone wedges (GZWs) are associated with mega-scale glacial lineations (MSGLs) (McMullen et al. 2006). GZWs form along ...
Predicting interactions between common dolphins and the pole-and-line tuna fishery in the Azores
(Public Library of Science, 2016-11-16)
Common dolphins (Delphinus delphis) are responsible for the large majority of interactions with the pole-and-line tuna fishery in the Azores but the underlying drivers remain poorly understood. In this study we investigate ...
The spatial and temporal abundance patterns of chaetognaths in the western North Atlantic Ocean
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-08)
Zooplankton samples were collected with the MOCNESS (Multiple Opening/ Closing Net and Environmental Sensing System) on six cruises in the western North Atlantic Ocean during the period from August 1975 to November 1977 ...
Submeter bathymetric mapping of volcanic and hydrothermal features on the East Pacific Rise crest at 9°50′N
(American Geophysical Union, 2007-01-19)
Recent advances in underwater vehicle navigation and sonar technology now permit detailed mapping of complex seafloor bathymetry found at mid-ocean ridge crests. Imagenex 881 (675 kHz) scanning sonar data collected during ...
The nutritional role of endosymbiotic bacteria in animal-bacteria symbioses : Solemya velum, a case study
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-08)
The trophie interactions occurring between endosymbiotic bacteria and the host in animal-bacteria symbioses were investigated using the endosymbiont-containing protobranch clam, Solemya velum, as a general model. C, N, ...
Functional characterization and expression of molluscan detoxification enzymes and transporters involved in dietary allelochemical resistance
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-06)
Understanding how organisms deal with potentially toxic or fitness-reducing allelochemicals is important for understanding patterns of predation and herbivory in the marine environment. The ability of marine consumers ...
Deep-sea mining of seafloor massive sulfides
The potential emergence of an ocean mining industry to exploit seafloor massive sulfides could present opportunities for oceanographic science to facilitate seafloor mineral development in ways that lessen environmental harms.
