Hydrothermal Discharge During Submarine Eruptions: The Importance of Detection, Response, and New Technology [PDF]

Oceanography, 2012
Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to ...

Compositional trends of Icelandic basalts: Implications for short–length scale lithological heterogeneity in mantle plumes

Lithological variations in the mantle source regions under mid-ocean ridges and ocean islands have been proposed to play a key role in controlling melt generation and basalt composition.

Range extension and first records of Coryphaenoides striaturus Barnard, 1925 and Coryphaenoides subserrulatus Makushok, 1976 (Macrouridae: Gadiformes) in Brazilian waters, Southwest Atlantic, using integrative taxonomy

Journal of Fish Biology, EarlyView.
Abstract Coryphaenoides Gunnerus, 1765 comprises 66 valid species of deep‐sea fishes commonly known as grenadiers, with 6 previously reported from Brazilian waters. Here, we make the first records for Coryphaenoides striaturus and Coryphaenoides subserrulatus on the Brazilian continental slope. Both species are distributed in the subtropical regions of

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

Journal 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

, 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]

, 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 ...

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

Journal 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

Marine 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.

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

Geophysical 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

The chemistry of iron in hydrothermal plumes

, 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 ...
