Abstract Marine heatwaves (MHWs)—periods of exceptionally warm ocean temperature lasting weeks to years—are now widely recognized for their capacity disrupt marine ecosystems 1–3 . The substantial ecological and socioeconomic impacts these extreme events present significant challenges resource managers 4–7 , who would benefit from forewarning MHWs facilitate proactive decision-making 8–11 However, despite extensive research into the physical drivers 11,12 there has been no comprehensive...
Abstract As the urgency to evaluate impacts of climate change on marine ecosystems increases, there is a need develop robust projections and improve uptake ecosystem model outputs in policy planning. Standardizing input output data crucial step evaluating communicating results, but can be challenging when using models with diverse structures, assumptions, that address region‐specific issues. We developed an implementation framework workflow standardize fishing forcings used by regional...
Historical hydrographic data (1984–2012) from the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program and global reanalysis products were used to quantify recent water mass variability off coast of Southern California. Dissolved oxygen concentrations continued decline within lower pycnocline, concurrent with strong increases in nitrate phosphate that have spatial patterns matching those dissolved oxygen. Silicic acid also shows an increasing trend offshore portion...
Given the ecological and economic importance of eastern boundary upwelling systems like California Current System (CCS), their evolution under climate change is considerable interest for resource management. However, spatial resolution global earth system models (ESMs) typically too coarse to properly resolve coastal winds dynamics that are key structuring these ecosystems. Here we use a high-resolution (0.1°) regional ocean circulation model coupled with biogeochemical dynamically downscale...
Marine ecosystem forecasting is an area of active research and rapid development. Promise has been shown for skillful prediction physical, biogeochemical, ecological variables on a range timescales, suggesting potential forecasts to aid in the management living marine resources coastal communities. However, mechanisms underlying forecast skill ecosystems are often poorly understood, many forecasts, especially biological variables, rely empirical statistical relationships developed from...
Abstract Efforts to manage living marine resources (LMRs) under climate change need projections of future ocean conditions, yet most global models (GCMs) poorly represent critical coastal habitats. GCM utility for LMR applications will increase with higher spatial resolution but obstacles including computational and data storage costs, obstinate regional biases, formulations prioritizing robustness over skill persist. Downscaling can help address limitations, significant improvements are...
Projecting the future distributions of commercially and ecologically important species has become a critical approach for ecosystem managers to strategically anticipate change, but large uncertainties in projections limit climate adaptation planning. Although distribution are primarily used understand scope potential change-rather than accurately predict specific outcomes-it is nonetheless essential where why can give implausible results identify which processes contribute uncertainty. Here,...
Abstract The Blob was the early manifestation of Northeast Pacific marine heat wave from 2013 to 2016. While upper ocean temperature in has been well described, impacts on biogeochemistry have not fully studied. Here, we characterize and develop understanding Eastern North biogeochemical properties during Winter 2013–2014 using situ observations, an observation‐based product, reconstructions a collection models. We find that is associated with significant anomalies: A 5% increase aragonite...
ABSTRACT Climate change can impact marine ecosystems through many biological and ecological processes. Ecosystem models are one tool that be used to simulate how the complex impacts of climate may manifest in a warming world. In this study, we an end‐to‐end Atlantis ecosystem model compare contrast effects climate‐driven species redistribution projected temperature from three separate on key commercial importance California Current Ecosystem. Adopting scenario analysis approach, measure...
Climate change and the associated shifts in species distributions ecosystem functioning pose a significant challenge to sustainability of marine fisheries human communities dependent upon them. In California Current, as recent, rapid, widespread changes have been observed across regional ecosystems, there is an urgent need develop implement adaptive climate-ready management strategies. Vulnerability Assessments (CVA) proposed first-line approach towards allocating limited resources...
Many coastal areas host rich marine ecosystems and are also centers of economic activities, including fishing, shipping recreation. Due to the socioeconomic ecological importance these areas, predicting relevant indicators ecosystem state on sub-seasonal interannual timescales is gaining increasing attention. Depending application, forecasts may be sought for variables spanning physics (e.g., sea level, temperature, currents), chemistry nutrients, oxygen, pH), biology (from viruses top...
Abstract Many marine species are shifting their distributions in response to changing ocean conditions, posing significant challenges and risks for fisheries management. Species distribution models (SDMs) used project future the face of a climate. Information fit SDMs generally comes from two main sources: fishery‐independent (scientific surveys) fishery‐dependent (commercial catch) data. A concern with data is that fishing locations not independent underlying abundance, potentially biasing...
Climate change drives species distribution shifts, affecting the availability of resources people rely upon for food and livelihoods. These impacts are complex, manifest at local scales, have diverse effects across multiple species. However, wild capture fisheries, current understanding is dominated by predictions individual coarse spatial scales. We show that species-specific responses to localized environmental changes will alter collection co-occurring within established fishing...
Parents' engagement in their children's education is key to academic success and social development. For many parents the U.S., still a struggle partly due lack of communication community-building tools that support broader ecology parenting, or parental ecology. Although current technologies have potential create opportunities improve engagement, little known about impact existing technology's design on We present findings from 63 interviews with an observation parent-school interactions....
Climate change may impact ocean ecosystems through a number of mechanisms, including shifts in primary productivity or plankton community structure, acidification, and deoxygenation. These processes can be simulated with global Earth system models (ESMs), which are increasingly being used the context fisheries management other living marine resource (LMR) applications. However, projections LMR-relevant metrics such as net production vary widely between ESMs, even under identical climate...
Motivated by a need for climate-informed living marine resource management, increased emphasis has been placed on regional end-to-end modeling frameworks designed to project climate impacts ecosystems and evaluate the efficacy of potential management strategies under changing conditions. The 'Future Seas' was initiated with focus three fisheries (Pacific sardine, swordfish, albacore tuna) in California Current System (CCS). This work leverages suite climate, ocean, ecosystem, economic models...

Abstract In the California Current System (CCS), changes in phenology (i.e., seasonal timing) of coastal upwelling alter functioning this productive marine ecosystem. Recently developed indices that account for strength and nutrient flux to surface provide a more complete understanding bottom‐up forcing region. Using these indices, we describe CCS phenological variability vertical transport flux. Physical biogeochemical spring transitions generally co‐occur winter or spring, followed by...
ABSTRACT Changing ocean conditions are leading to spatial redistribution of many marine species, including those that support fisheries. A combination gradual climate trends and shorter‐lived extreme events, such as heatwaves, can change the availability species or stocks fishing ports, impacting communities challenging fisheries management frameworks. Pacific sardine ( Sardinops sagax ) in California Current System currently considered two subpopulations for purposes. They separated from...
