Improving Satellite-derived Bathymetry

, 2016
Bathymetry is traditionally acquired using singlebeam or multibeam echosounders. This method produces accurate depth measurements along transects but is constrained by operating cost and an inability to survey in very shallow waters. Airborne Lidar is able to produce accurate bathymetric information over clear waters at depths up to 70m, but can be ...

Development of a Mesoscale‐ and Tide‐Resolving Ocean–Biogeochemistry Model for the Pacific: Tidal Enhancement of the Biological Carbon Pump

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract This study presents a new physical‐biogeochemical simulation of the Pacific Ocean that resolves mesoscale dynamics and explicitly includes tidal forcing. The primary objective is to develop and document a modeling framework that serves both as a detailed record of model configuration and forcing preparation, and as a reference for future ...

A Phenoregion Approach to Understanding Chlorophyll‐a Seasonal Cycles and Interannual Variability in the South‐West Indian Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The South‐West Indian Ocean (SWIO) displays marked spatial variations in physical forcings, driving in turn distinct seasonal biogeochemical regimes. Mesoscale eddies in the Mozambique Channel drive large‐scale redistribution of nutrients and plankton, while eastern Madagascar waters are highly oligotrophic.

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.

Satellite-derived bathymetry using Sentinel-2 in mesotidal coasts

Coastal Engineering
Coastal zones are strategic environments of high socioeconomic, political, and ecological value, with over half of the world's population residing within 200 km of the coast. This proximity highlights their vulnerability to extreme events, which are exacerbated by global changes, leading to significant coastal impacts such as erosion, flooding, and ...

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)

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.
