Abstract. Coastal and estuarine waters of the northern California Current system southern Salish Sea host an observational network capable characterizing biogeochemical dynamics related to ocean acidification, hypoxia, marine heatwaves. Here, we compiled data sets from a set cruises conducted in Puget Sound (southern Sea) its boundary (Strait Juan de Fuca Washington coast). This product provides decade with consistent formatting, extended quality control, multiple units for parameters such as oxygen different end use needs conventions. All obtained high-quality temperature, salinity, inorganic carbon, nutrient, observations provide insight into dynamic distribution physical conditions this large urban estuary complex on west coast North America. At all sampling stations, conductivity–temperature–depth (CTD) casts included sensors measuring conductivity, pressure, concentrations.

Can Seasonal Forecasts of Ocean Conditions Aid Fishery Managers? Experiences from 10 Years of J-SCOPE

Oceanography, Journal Year: 2023, Volume and Issue: unknown

Published: Jan. 1, 2023

Multiple stressors co-occurring in coastal waters are of increasing concern to local fisheries. Many economically, culturally, or ecologically important species (e.g., oysters, crabs, pteropods) the Pacific Northwest already directly affected by ocean acidification (OA), warming, and hypoxia. Additional indirect economic impacts on finfish industry possible due losses prey species. Because strong seasonal interannual variations conditions, capability for predicting degrees hypoxia, as well relevant indices impact interest, could be considerable benefit managers. Over past 10 years, we have developed a prediction system, JISAO’s Seasonal Coastal Ocean Prediction Ecosystem (J-SCOPE), Northwest. The goal has been provide (six-month) predictions conditions that testable management decisions regarding fisheries, protected species, ecosystem health. results this work include publicly available forecasts OA variables, temperature, ecological indicators tailored decision-makers involved federal, international, state, tribal We codesigned J-SCOPE model products with state managers, now federal managers at Fishery Management Council receive hypoxia within their annual Status Reports.

Predation scars provide a new method to distinguish native and invasive crab predation on mollusc prey

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(9)

Published: Sept. 1, 2024

Abstract Crab species are increasingly important socioeconomic resources that threatened by human exploitation, climate change, and invasive species, such as European green crabs ( Carcinus maenas ). However, the continued health of their populations is often uncertain given limited long‐term population data, necessitating alternate approaches to ensure viability. Furthermore, C. one most highly destructive marine globally, posing a threat local ecosystems including socioeconomically mollusc prey. Improved understanding invasions impacts on crab therefore vitally important.

Ocean acidification thresholds for decapods are unresolved

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: Nov. 15, 2024

A published analysis of ocean acidification thresholds for decapod crustaceans highlights data showing the negative effects low pH on many species. However, methods used in paper have substantial flaws that call into question proposed thresholds. The quantitative metrics calculated meta-analysis are uninformative with respect to sensitivity, which raises concerns about validity developed by expert opinion process. We recommend against using and a reanalysis identify new

The History and Evolution of PMEL: Purposeful Research that Impacts Environmental Policy

Oceanography, Journal Year: 2023, Volume and Issue: unknown

Published: Jan. 1, 2023

The Pacific Marine Environmental Laboratory (PMEL) conducts global and regional oceanographic research in support of the National Oceanic Atmospheric Administration’s (NOAA’s) three mission areas: (1) understanding predicting changes climate, weather, oceans, coasts; (2) sharing that knowledge with others; (3) conserving managing coastal marine ecosystems resources. Since its establishment 1973, PMEL’s work has ranged from pole to across ocean. lab’s examined ocean structure function physical, chemical, biological realms, informed supported development US policy these areas.
