Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

RRS James Cook Cruise 35, 7-19 Jun 2009. Sidescan sonar mapping of the Whittard Canyon, Celtic Margin [PDF]

, 2009
James Cook cruise 035 was aimed at the detailed mapping of the Whittard Canyon system along the Celtic Margin (NE Atlantic). In 12 days, >700 km of track-lines were surveyed with the Towed Ocean Bottom Instrument (TOBI, carrying a 30 kHz sidescan sonar

Submarine canyons: Internal wave traps?

Geophysical Research Letters, 1976
Kinetic energy of water currents near the axis of La Jolla submarine canyon is enhanced in a broad frequency band above tidal frequencies and below the Väisälä frequency when compared with water motions nearby but not within the canyon. This energy appears to be derived from first mode internal waves over the adjacent continental shelf.

Population Demographics of Killer Whales (Orcinus orca) in Western Australia

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer

Sediment dynamics and geohazards offshore Uruguay and northern Argentina: first results from the multi-disciplinary Meteor-cruise M78-3 [PDF]

, 2010
About 90% of the sediments generated by weathering and erosion on land get finally deposited at the ocean margins. The sediment distribution processes and landscape evolution on land are relatively well understood, but comparably little is known about ...

Characterizing the Distribution and Behavior of Sperm Whales, Physeter macrocephalus, Over the Otago Submarine Canyons, New Zealand

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Sperm whales (Physeter macrocephalus) play an important role in marine ecosystems as top predators, nutrient vectors, and indicators of ecosystem health. In Aotearoa New Zealand, sperm whales remain largely understudied other than at Kaikōura, a foraging area for males.

Quaternary gas hydrate dissociation promotes the formation of Shenhu Canyon Group in the South China Sea

Frontiers in Marine Science
The Baiyun deepwater region (Shenhu area) of the Pearl River Mouth Basin (PRMB), northern South China Sea (SCS), is characterized by the presence of abundant gas hydrate deposits and dense submarine canyons. However, the relationships between gas hydrate

Living Near the Surface: Dive Behavior of Sei Whales (Balaenoptera borealis) in the Southwestern Atlantic Ocean

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding the diving behavior of baleen whales in tropical breeding areas is essential for evaluating both ecological functions and anthropogenic threats. In this study, we combined satellite transmitters and generalized additive mixed models (GAMMs) to investigate the dive behavior of sei whales (Balaenoptera borealis) in Santos Basin (SB)

Deep-water turbidites as Holocene earthquake proxies: the Cascadia subduction zone and Northern San Andreas Fault systems [PDF]

, 2003
New stratigraphic evidence from the Cascadia margin demonstrates that 13 earthquakes ruptured the margin from Vancouver Island to at least the California border following the catastrophic eruption of Mount Mazama.

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, Volume 73, Issue 3, Page 620-644, April 2026.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.
