Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the tropical and the subtropical Atlantic representative of different water bodies (NE Brazil shelf,

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

New Fishing Strategies to Face Climate Change Effects on the Spanish Tropical Tuna Fisheries Off Indian Ocean

open access: yesFisheries Oceanography, Volume 34, Issue 6, Page 17-26, November 2025.
ABSTRACT Tropical tunas, including yellowfin (Thunnus albacares), are recognized as a crucial contributor to global food security. Moreover, yellowfin tuna is the most commercially valuable tropical tuna. The Spanish purse seine freezer fleet, actively operating in the Indian Ocean, emerges as a leading contributor to the global yellowfin tuna catch ...

Time Series of the Canary Current Derived From One Year of Pressure Inverted Echo Sounder (PIES) Data

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract Five pressure inverted echo sounders (PIES) have been deployed north of the Canary Islands at a nominal latitude of 29°N for 1 year to estimate a time series of volume transport of the Canary Current (CC) and the Lanzarote passage (LP) using the gravest empirical method (GEM).
