Behaviour and Dispersal of Mobile Salmon Lice When Detached From the Host

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Sea lice can flourish when salmon are farmed in open sea‐cages, necessitating treatments to control outbreaks and reduce larval export. However, mobile ectoparasitic stages can be dislodged during crowding or other procedures, and potentially reinfest farmed or wild fish.

Studies of oceanic tectonics based on GEOS-3 satellite altimetry [PDF]

open access: yes
Using statistical analysis, geoidal admittance (the relationship between the ocean geoid and seafloor topography) obtained from GEOS-3 altimetry was compared to various model admittances.

The estimation of geoacoustic properties from broadband acoustic data, focusing on instantaneous frequency techniques [PDF]

open access: yes, 2002
The compressional wave velocity and attenuation of marine sediments are fundamental to marine science. In order to obtain reliable estimates of these parameters it is necessary to examine in situ acoustic data, which is generally broadband.

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

open access: yesJournal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Mantle Exhumation and Post‐Rift Magmatism at an Oblique Magma‐Poor Continental Margin

open access: yesGeophysical Research Letters
Continental breakup is a fundamental tectonic process, which leads to seafloor spreading and the generation of oceanic crust. However, the current understanding of continental margins, based largely on 2‐D seismic transects, is inadequate to capture the ...

Long lifespan and substantial biomass production support stable high biomass of Ascophyllum nodosum under interannual climate fluctuations in Greenland

open access: yesJournal of Phycology, EarlyView.
Abstract The brown macroalga Ascophyllum nodosum is a foundation species on intertidal rocky shores, where its perennial canopy and high productivity support key ecological functions. However, its population dynamics near the northern edge, where low temperatures and sea ice may challenge stability, are largely unknown.

Near bottom sediment characterization offshore SW San Clemente Island [PDF]

open access: yes, 2002
Normal incidence, 23.5 kHz seafloor acoustic backscatter data and bottom video were measured with the Deep Tow instrument package of the Scripps Institution of Oceanography in 100 meter water depth south of San Clemente Island, CA.
