The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Fuzzy Clustering for Seafloor Classification

open access: yes, 2009
In order to develop quantitative seafloor sediment classification techniques it is important to acknowledge that by nature the boundaries between soft sediments are characterized by transition zones and therefore are indeterminate and gradual.

Separating Faces in ARMS Metabarcoding Improves Marine Biodiversity Monitoring: A Comparison Across Protocols, Experimental Designs and Photographic Surveys

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Monitoring marine biodiversity requires approaches capable of capturing its spatial and temporal complexity. DNA metabarcoding coupled with Autonomous Reef Monitoring Structures (ARMS) is increasingly used for this purpose, yet most applications still pool all sessile fractions and rarely benchmark molecular outputs against photographic ...

Target Capture of Ancient Shell DNA Enables Phylogenetic Reconstruction of Deep‐Sea Molluscs

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates remains poorly understood. Here, we compared DNA recovery from four fresh and 12 ancient (eight radiocarbon‐dated to 1671–1135 years old before ...

Diffuse attenuation coefficient and bathymetry retrieval in shallow water environments by integrating satellite laser altimetry with optical remote sensing

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Shallow water environmental information is crucial for the study of marine ecosystems and human activities. There have been numerous satellite remote sensing studies focused on this area. However, accurate information acquisition from remote sensing data

Tracking the impact of bottom trawling on benthic habitat status

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Structural Variation in Whistle Patterns of Two Coastal Dolphin Species Co‐Occurring in the Southern Israeli Mediterranean Sea

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...

Seafloor classification using the RoxAnn ground-discrimination system and a new tool for visualization and classification

open access: yes, 2012
Acoustic investigation of the seafloor is a widespread tool to understand the sedimentary processes that move sediments and that lead to the formation of distinct bedforms and habitats.
