Field studies were conducted to assess the coastal water quality impact of stormwater runoff from Santa Ana River, which drains a large urban watershed located in southern California. Stormwater river leads very poor surf zone quality, with fecal indicator bacteria concentrations exceeding California ocean bathing standards by up 500%. However, cross-shore currents (e.g., rip cells) dilute contaminated cleaner offshore, such that contamination is generally confined < 5 km around outlet....
The Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission was recommended by the National Research Council's (NRC's) Earth Science Decadal Survey to measure tropospheric trace gases aerosols coastal ocean phytoplankton, water quality, biogeochemistry from geostationary orbit, providing continuous observations within field of view. To fulfill mandate address challenge put forth NRC, two GEO-CAPE Working Groups (SWGs), representing atmospheric composition color disciplines, have...
The paper gives an overview of the development satellite oceanography over past five years focusing on most relevant issues for operational oceanography. Satellites provide key essential variables to constrain ocean models and/or serve downstream applications. New and improved data sets have been developed directly quality products. status constellation last was, however, not optimal. Review future missions shows clear progress new research with a potentially large impact should be...
Recent and forthcoming launches of a plethora ocean color radiometry sensors, coupled with increasingly adopted free open data policies are expected to boost usage satellite drive the demand use these in quantitative routine manner. Here we review factors that introduce uncertainties various satellite-derived water quality products recommend approaches minimize uncertainty specific product. We show regression relationships between remote-sensing reflectance turbidity (in terms nephelometric...
This study describes the characteristics of extensive small‐scale coastal ocean eddies in Southern California Bight. These surface features were primarily detected by using ERS‐1 and ERS‐2 synthetic aperture radar (SAR) satellite imagery from 1992 to 1998. The eddies, predominantly cyclonic their rotation, appeared result several forcing mechanisms. They mainly observed within Santa Barbara Channel Monica‐San Pedro Basin regions be seasonal distribution. Observed eddy diameters all less than...
Remote sensing of chlorophyll-a concentration, [Chl-a], has been difficult in coastal waters like the Chesapeake Bay owing largely to terrestrial substances (such as minerals and humus) that are optically significant but do not covary with phytoplankton. Here we revisit semi-analytical pathway deriving [Chl-a] based on light absorption coefficient phytoplankton by introducing generalized stacked-constraints model (GSCM) partition satellite-derived total water (with pure-water contribution...
Wind‐ and current‐induced island wakes were investigated using a multiplatform approach of in situ, remote sensing, numerical model simulations for the Southern California Bight (SCB). Island wind are result sheltering from wind, with weak mixing, strong heat storage, consequent high sea surface temperature (SST). Wind around Santa Catalina most persistent during spring summer months. Current wakes, caused by disruption poleward traveling Countercurrent, induce eddies to form off north end...
Abstract Seawind is essential in studying extreme weather and climate events globally over the oceans. It has significant impacts through air–sea interactions, upper ocean mixing, energy flux generation. The sea surface wind also a critical element blue economy strategic planning, offshore renewable energy, marine transportation, ecosystem, fisheries. As per Intergovernmental Panel on Climate Change (IPCC) working group report, there low confidence level trends due to insufficient evidence....
Abstract We present a model, referred to as Generalized Stacked‐Constraints Model (GSCM), for partitioning the total light absorption coefficient of natural water (with pure‐water contribution subtracted), nw (λ), into phytoplankton, ph nonalgal particulate, d and CDOM, g components. The formulation model is based on so‐called stacked‐constraints approach, which utilizes number inequality constraints that must be satisfied simultaneously by outputs component coefficients. A major advancement...

Abstract The primary cause of coastal hypoxia is generally attributed to phytoplankton blooms and their subsequent benthic decay. However, direct linkages between have been rarely reported. Here using satellite field data, we show that such exist in the Chesapeake Bay. For deeper ( 10 m) but nonhypoxic stations, bottom dissolved oxygen significantly correlated with surface algal biomass during preceding weeks. Optimal correlation exhibits a bimodal seasonal variation two peaks April August,...
Abstract This study investigated trends in satellite-based chlorophyll-a (Chl-a; 1998–2022), sea surface temperature (SST; 1982–2022), and level anomaly (SLA; 1993–2021) from the European Space Agency’s Climate Change Initiative records, integrating time series decomposition spectral analysis. Trends parameters signify prolonged increases, decreases, or no changes over time. These are same space as original parameters, excluding seasonalities noise, can exhibit nonlinearity. Trend rates...
Repeat sampling on hourly time scales using an airborne synthetic aperture radar (SAR) is used to investigate the occurrence and evolving characteristics of spiral‐shaped slick patterns, commonly presumed be indicators submesoscale ocean eddies, in area around Santa Catalina Island, California (∼33.4°N, 118.4°W). Simultaneous SAR imagery boat survey data are examined over two ∼5 h long periods spaced 3 days apart April 2003. The reveals several spiral‐like roughly 5 km diameter, occurring...
In response to its users’ needs, the National Oceanic and Atmospheric Administration (NOAA) initiated reanalysis (RAN) of Advanced Very High Resolution Radiometer (AVHRR) Global Area Coverage (GAC; 4 km) sea surface temperature (SST) data employing Clear Sky Processor for Oceans (ACSPO) retrieval system. Initially, AVHRR/3 from five NOAA two Metop satellites 2002 2015 have been reprocessed. The derived SSTs matched up with reference SSTs—the quality controlled in situ Quality Monitor (iQuam)...
