Volcano-tectonic interactions revealed by inversion of focal mechanisms: stress field insight around and beneath the Vatnajökull ice cap in Iceland

open access: yesFrontiers in Earth Science, 2014
Volcano-tectonic processes in the central part of Iceland, covered by the Vatnajökull glacier, are investigated by inversion of focal mechanisms. Working on a large catalogue of focal mechanisms determined by the Icelandic Meteorological Office, we used ...

On the occurrence of the snakefish Trachinocephalus myops (Aulopiformes: Synodontidae) in the Azores archipelago

open access: yesJournal of Fish Biology, EarlyView.
Abstract The snakefish Trachinocephalus myops is an Atlantic species distributed in tropical and temperate coastal waters on sandy substrates. This study reports the validated record of an adult T. myops in the Azores archipelago caught by a fisherman at Faial Island.

Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets [PDF]

open access: yesOceanography, 2012
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate approaches are sometimes needed.

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

open access: yesJournal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

open access: yesJournal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

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

open access: yesJournal 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

Lava Geochemistry as a Probe into Crustal Formation at the East Pacific Rise [PDF]

open access: yesOceanography, 2012
Basalt lavas comprise the greatest volume of volcanic rocks on Earth, and most of them erupt along the world's mid-ocean ridges (MORs). These MOR basalts (MORBs) are generally thought to be relatively homogeneous in composition over large segments of the

Velocity sections of the upper mantle under the oceans

open access: yesГеофизический журнал, 2016
We constructed the models of the distribution of longitudinal seismic waves velocities for the upper mantle oceanic regions: mid-ocean ridges (MOR), basins, trenches, island arcs and coastal ridges, back-arc troughs (BAT).
