Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

A single-station method for the detection, classification and location of fin whale calls using ocean-bottom seismic stations

open access: yes, 2015
Passive seismic monitoring in the oceans uses long-term deployments of Ocean Bottom Seismometers (OBSs). An OBS usually records the three components of ground motion and pressure, typically at 100Hz.

Geochemical and Visual Indicators of Hydrothermal Fluid Flow through a Sediment-Hosted Volcanic Ridge in the Central Bransfield Basin (Antarctica) [PDF]

open access: yes, 2013
In the austral summer of 2011 we undertook an investigation of three volcanic highs in the Central Bransfield Basin, Antarctica, in search of hydrothermal activity and associated fauna to assess changes since previous surveys and to evaluate the extent ...

Persistent Heterogeneities in the Oceanic Lithosphere Due To Differential Freezing Beneath Ridges

open access: yesGeophysical Research Letters
Oceanic lithosphere, which forms two‐thirds of Earth's surface, is generated at mid‐ocean ridge spreading centers. Yet the internal structure of the lithosphere is not well characterized and often considered to be homogeneous relative to the structure of

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

The chemistry of iron in hydrothermal plumes

open access: yes, 2008
This thesis investigates the role of submarine hydrothermal vents in the global marine Febudget. While debate continues over the sources of dissolved Fe to the global deep-oceandissolved Fe budget, it had been presumed, until recently, that all the Fe ...

Crustal structure of the spreading plate boundary in Iceland and the north Atlantic from gravity data [PDF]

open access: yes, 1994
Gravity datasets from two geothermal areas in Iceland, an Iceland-wide gravity dataset, and marine gravity data from the Reykjanes Ridge at 58˚N, which can be seen as the submarine extension of the Icelandic accretionary system, have been studied in this

Impact of geothermal heating on the global ocean circulation

open access: yes, 2001
The response of a global circulation model to a uniform geothermal heat flux of 50 mW m-2 through the sea floor is examined. If the geothermal heat input were transported upward purely by diffusion, the deep ocean would warm by 1.2°C. However, geothermal

That sinkin’ feeling: Environmentally induced distress on a disappearing island

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent
