A framework for reconstructing marine heatwaves from individual foraminifera in sedimentary archives

Frontiers in Marine Science
Marine heatwaves (MHWs) are warm sea surface temperature (SST) anomalies with substantial ecological and economic consequences. Observations of MHWs are based on relatively short instrumental records, which limit the ability to forecast these events on ...

Sea surface temperature calculated from alkenones for the last 285 ka with high-reolution Holocene of sediment core MD02-2529, Panama Basin

, 2012
This dataset contains an extended SST record based on alkenone from MD02-2529 core covering the last 285 ka (Rincón-Martínez et al., 2010, Paleoceanography), with a high-resolution Holocene record superseding for that period the lower resolution ...

Storage treatment and diluent cause inconsistencies in commonly used fluorometric microplate enzyme assays conducted with saltmarsh soils

Limnology and Oceanography: Methods, EarlyView.
Abstract Fluorometric enzyme assays are a tool for determining potential enzyme activity in soils. A wide array of methodological approaches is adopted by different studies, making comparisons difficult. An important consideration is whether assay conditions replicate the environment of the samples or optimize potential enzyme activity.

MusselFinder: Automated dreissenid mussel density estimation via robotic benthic imaging

Limnology and Oceanography: Methods, EarlyView.
Abstract Despite the widespread need to map the abundance of invasive quagga and zebra mussels (Dreissena spp.) in lakes and reservoirs worldwide, current methods remain limited by data collection and analysis bottlenecks. Autonomous underwater vehicles (AUVs) combined with machine learning (ML) offer a scalable remote sensing approach for estimating ...

Variaciones del sistema de surgencia de Punta Angamos (23 S) y la Zona de Mínimo Oxígeno durante el pasado reciente: Una aproximación desde el registro sedimentario de la Bahía Mejillones del Sur Variations of Punta Angamos upwelling system (23 S) and the Oxygen Minimum Zone during the recent past: An approximation from sedimentary record of Mejillones del Sur Bay

Revista Chilena de Historia Natural, 2003
Parámetros geoquímicos (carbono orgánico, sílice biogénica y cadmio) y petrográficos (materia orgánica) estudiados en un testigo de sedimento de la Bahía Mejillones del Sur fueron utilizados para inferir variaciones en la productividad biológica ...

Automatization of multistep sample preparation for microplastics monitoring in aquatic environments

Limnology and Oceanography: Methods, EarlyView.
Abstract Microplastics (MP) have been found in every environmental compartment in urban and remote areas. Although their ubiquity is widely recognized, the lack of harmonized protocols for sampling, sample preparation, and particle identification/quantification hinders comparability among studies.

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

Limnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.
