Higher survival but smaller size of juvenile Dungeness crab (<em>Metacarcinus magister</em>) in high CO<sub>2</sub>
Dungeness crab (Metacarcinus magister) are the most valuable fishery on the U.S. West Coast and both larval and adult Dungeness crabs are important components of regional food webs. Previous experiments have shown decreased survival and a slower development rate for Dungeness crab zoea reared in water with high CO2, indicating a susceptibility to ocean acidification.
Net ecosystem dissolution and respiration dominate metabolic rates at two western Atlantic reef sites
Ocean acidification is changing surface water chemistry, but natural variability due to nearshore processes can mask its effects on ecosystem responses. We present an approach of quantitatively resolving net ecosystem metabolism from an array of long-term time series stations, offering perhaps the longest record of such processes over a reef to date. We used 8
Ocean Biogeochemical Signatures of the North Pacific Blob
The global ocean is experiencing major changes due to human-made carbon emissions and climate change, leading to a warming ocean with increasing acidity and declining oxygen. On top of these long-term changes in the ocean are short-term extreme events, such as marine heatwaves. These extreme events quickly change the ocean state and can stress marine

A framework for assessing harvest strategy choice when considering multiple interacting fisheries and a changing environment: The example of eastern Bering Sea crab stocks
Ecosystem Based Fisheries Management aims to broaden the set of factors included in assessments and management decision making but progress with implementation remains limited. We developed a framework that examines the consequences of temporal changes in temperature and ocean pH on yield and profit of multiple interacting stocks including eastern Bering Sea (EBS) snow, southern Tanner, and
Influence of Winter Subsurface on the Following Summer Variability in Northern California Current System
Temperature variations in the North and tropical Pacific contribute to the predictability of temperatures along the 26.4σ isopycnal layer off the Northern California Current System (N-CCS). Monthly temperature variations at this depth in the N-CCS are related to a linear combination of factors, including North Pacific spice anomalies, and the PDO and ENSO climate indices. However,
Climate downscaling for regional models with a neural network: A Hawaiian example
Global ocean/atmosphere circulation models (GCMs) allow us to better understand and predict the behavior of the ocean and atmosphere at large spatial and temporal scales; however, they may be unsuited for regional studies due to their low spatial resolution. We have developed a method for downscaling GCMs data using an artificial neural network to reconstruct

Characterizing Mean and Extreme Diurnal Variability of Ocean CO2 System Variables Across Marine Environments
Diurnal variability of ocean CO2 system variables is poorly constrained. Here, this variability and its drivers are assessed using 3-h observations collected over 8–140 months at 37 stations located in diverse marine environments. Extreme diurnal variability, that is, when the daily amplitude exceeds the 99th percentile of diurnal variability, is comparable in magnitude to the seasonal amplitude and
Reaching Consensus on Assessments of Ocean Acidification Trends
Scientists are working to establish a common methodology for evaluating rates of change in—and the various mechanisms that affect—acidification across ocean environments. This workshop was funded by NOAA’s Ocean Acidification Program

The Ocean Carbon Response to COVID-Related Emissions Reductions
The decline in global emissions of carbon dioxide due to the COVID-19 pandemic provides a unique opportunity to investigate the sensitivity of the global carbon cycle and climate system to emissions reductions. Recent efforts to study the response to these emissions declines has not addressed their impact on the ocean, yet ocean carbon absorption is
