The application of a proactive grooming program to manage the fouling control coatings applied to ship hulls provides an opportunity to address the climate crisis, invasive species and the discharge of biocides into the marine environment. A large percentage of the total power required to propel a ship is to overcome the viscous drag created between the hull and the water. The powering penalty due to increases in coating rough...

Successful recruitment of marine fishes depends on survival during early life‐history stages, which is influenced by oceanic advection due to its impact on coastal trophodynamics and transport processes. Here we evaluate the influence of ocean circulation on the dispersal of rockfish ( Sebastes spp.) larvae along the central California coast using an implementation of the Regional Ocean Modeling System, driven at the surface b...

Standard CalCOFI (California Cooperative Oceanic Fisheries Investigations) ichthyoplankton bongo net sampling was conducted every 2 h over 11 days at a single fixed station off central California in February 1995. A conductivity, temperature, and depth cast was completed after each tow to record corresponding hydrographic information. Larval Pacific hake, shortbelly rockfish, and other rockfish were enumerated and length measu...

We assessed growth in subyearling chinook salmon ( Oncorhynchus tshawytscha ) during the 1998 El Niño and 1999 La Niña in the Gulf of the Farallones, a region of the continental shelf off central California seaward of the Golden Gate and the southernmost ocean entry point for the species in North America. Juvenile salmon demonstrated greater growth during this strong El Niño, when water temperature anomalies of more than +3°C...

Juvenile Sebastes jordani individuals sampled in late spring 1995, 1996, and 1997 near Monterey Bay, California, were analyzed for Δ 14 C, Δ 13 C, and Δ 15 N. As anticipated, a strong negative correlation was found between mean annual juvenile rockfish Δ 14 C and the preceding 3‐month average Bakun upwelling index for this region. The sensitivity of this isotopic response by juvenile rockfish to upwelling variations was simila...

The diel and spatial distributions of postflexion larval Citharichthys spp. and Sebastes spp. at 67 stations off central California were examined during March 1994 with a 10 m 2 MOCNESS during 24 h sampling operations. At each station, a CTD profiler with an attached PAR sensor was deployed to measure temperature, salinity, σ t , dynamic height, and ambient light levels at depth. Catches of C. sordidus, C. stigmaeus, unidentif...

123°00′W) occurs primarily during relaxation from upwelling, when warm water flows poleward from the Gulf of the Farallones. During 1994 and 1995 we sampled planktonic larval distributions and hydrography both south and north of Point Reyes during upwelling to test whether high concentrations of crab and rockfish larvae were concentrated in the source of the relaxation flow to the south of Point Reyes. An upwelling plume off P...
