Abstract The 2015–2016 El Niño is by some measures one of the strongest on record, comparable to 1982–1983 and 1997–1998 events that triggered widespread ecosystem change in northeast Pacific. Here we describe impacts California Current System (CCS) place them historical context using a regional ocean model underwater glider observations. Impacts physical state CCS are weaker than expected based tropical sea surface temperature anomalies; density fields reflect persistence multiyear...
Abstract Large‐scale patterns of positive temperature anomalies persisted throughout the surface waters North Pacific Ocean during 2014–2015. In Southern California Current System, measurements by our sustained network underwater gliders reveal coastal effects recent warming. Regional upper ocean were greatest since initiation glider in 2006. Additional observed physical included a depressed thermocline, high stratification, and freshening; induced biological consequences changes vertical...
Abstract A data-constrained state estimate of the southern California Current System (CCS) is presented and compared with withheld Cooperative Oceanic Fisheries Investigations (CalCOFI) data assimilated glider over 2007–17. The objective this comparison to assess ability State Estimate (CASE) reproduce key physical features CCS mean state, annual cycles, interannual variability along three sections Underwater Glider Network (CUGN). assessment focuses on several oceanic metrics deemed most...
Abstract The data-assimilating California State Estimate (CASE) enables the explicit evaluation of spatiotemporally varying volume and heat budgets in coastal Current System (CCS). An analysis over 10 years CASE model output (2007–17) diagnoses physical drivers CCS mean state, annual cycles, 2014–16 temperature anomalies associated with a marine wave an El Niño event. largest terms mixed layer (from−50 to 0 m) are upward vertical transport at coast offshore-flowing ageostrophic Ekman...
Abstract In the California Current System, cross‐shore transport of upwelled, nutrient‐rich waters from coastal margin to open ocean can occur within intermittent, submesoscale‐to‐mesoscale features such as filaments. Time‐varying spatial gradients filaments affect net fluxes physical, biological, and chemical tracers but require high‐resolution measurements accurately estimate. June 2017, Ecosystem Long Term Ecological Research program process cruise (P1706) conducted repeat sections by an...
Ocean boundary currents are complex and highly variable systems that play key roles in connecting the open coastal ocean through cross-slope circulation upwelling of nutrient-rich water. The structure, strength, variability associated with a broad range spatial temporal scales. For reason, long-term current monitoring is challenging requires use complementary observing platforms sensors coupled numerical simulations.
