Oceanography: CINMS

Overview

Water circulation around the Channel Islands is complex and highly dynamic, resulting from the interaction of large-scale ocean currents, local geography, and the unique basin and ridge topography of the ocean bottom in the Southern California Bight (SCB).

The California Current is a major ocean current that moves through the sanctuary region, staying largely to the west of the islands, but influencing the circulation patterns in the region. Year round, this current brings cold water from upwelling centers along the California coast.

At Point Conception, where the coastline turns east, the California Current moves farther offshore as it continues its southward flow. Near the U.S.- Mexican border the California Current turns east and then north, and flows back up along the coast bringing warm water into the Santa Barbara Channel. This directional shift creates a large eddy known as the Southern California Countercurrent or the Southern California Eddy (Hickey 2000a). At the eastern end of the Channel Islands, the Southern California Countercurrent separates into two parts. One part flows northwestward through the Santa Barbara Channel; the other part flows westward south of the Channel Islands. The California Current and Southern California Countercurrent are both strongest in the summer (Hickey 1993). During the spring, the countercurrent disappears and surface flow throughout the SCB tends to be southward (Hickey 1993). The timing, duration and intensity of upwelling events is driven by seasonal variations in wind direction and climatic variability associated with events such as El Nino. In general, upwelling period begins in March, when westerly winds prevail, and continues until September, when the winds die down (California Coastal Commission 1987).

Upwelling (circulation patterns in which deep, cold, nutrient-laden water moves towards the surface) often occurs where these currents meet. Upwelling currents influence circulation in the sanctuary region. These currents are the result of prevailing winds and the orientation of the coastline. Along the north-south oriented coast of California, winds blowing from the north move surface water westward, away from the coastline, and create upwelling currents that bring colder water to the surface.

Point Conception is the southernmost major upwelling center on the west coast of the United States, and marks a transition zone between cool surface waters to the north and warm waters to the south (Love et al. 1999). However, upwelled water from regions north of the SCB appears to enter the western end of the Santa Barbara Channel and move eastward along its southern boundary (Hickey 2000a). Between the islands and the mainland, these currents create a localized cyclonic gyre that can vary in intensity seasonally based on current and wind speed (Hendershot and Winant 1996, Harms and Winant 1998, Winant et al 2003). These varying conditions create alternate states of upwelling, where cool nutrient- rich water is brought from deeper areas to the photic zone at the surface, and relaxation, when upwelling ceases (Winant et al 2003). Regional upwelling is wind-driven and provides the nutrients and conditions for phytoplankton and zooplankton to thrive, with effects seen throughout the food chain.

Biogeographic Assessment of the Channel Islands National Marine Sanctuary

The Channel Islands National Marine Sanctuary (CINMS) off the coast of Southern California was designated in 1980. In 2005, NOAA's Office of National Marine Sanctuaries and CINMS were considering six alternatives for adjusting the sanctuary's boundaries. Identifying how the six options overlaid with the distribution of marine resources was a critical consideration. To address this need, we conducted a biogeographic assessment.

California Cooperative Oceanic Fisheries Investigations (CalCOFI)

The California Cooperative Oceanic Fisheries Investigations (CalCOFI) was formed in 1949 to study the ecological aspects of the Pacific sardine population collapse off California. Today, the focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change.

Characterizing ocean pH in the Channel Islands National Park

Managing the global threat of ocean acidification on a local scale is becoming a concern for policy makers and managers. With few long-term and baseline ocean pH records in place, it is difficult to understand natural and anthropogenic influences on pH variability. With development of pH sensors, monitoring networks are growing along the west coast of the United States.

Investigation of submerged shorelines in the Channel Islands and California Borderland

The Ocean Exploration Trust used scuba diving, high resolution autonomous surface vessel and ship-based mapping, and remotely operated vehicles to locate and characterize submarine shoreline terraces in the Channel Islands. Our 2017 team will continue their efforts in 2018 and will focus on: (1) locating sea caves at the 103-meter, 110-meter, and 120-meter paleo-shorelines on other submerged banks in the Borderland where the E/V Nautilus has subsequently collected bathymetric and backscatter maps since the 2017 cruise; (2) mapping the interior of several of the caves using a diver guided 3D imaging system; (3) using the ASV to locate possible cave entrances along deeper paleo-shorelines, (4) following that effort with a visual inspection of any new caves using the ROVs, and finally; (5) collecting water and/or sediment samples within selected caves to better understand the fish populations living within the caves through eDNA analysis.

Saildrone West Coast Ecosystem Survey

Saildrone provides high-resolution ocean data via a fleet of unmanned surface vehicles (USVs) to NOAA, the Department of Defense, and other US agencies. Saildrone’s USVs are wind-powered vehicles capable of long duration ocean missions (up to 12 months) and carry a sophisticated solar-powered sensor package that streams real-time data to cost-efficiently augment ship-based methods. Saildrone USVs are 23 feet long and 20 feet high, can be launched from any dock, and travel at an average speed of 3-5 knots. The USVs weigh 1200 lbs and have a 7 ft draft.

Santa Barbara Sediment Trap Time-Series Program

Since August 1993, a moored sediment trap has been located near the center of the Santa Barbara Basin (SBB) (34˚14' N, 120˚02'W). Over the course of the time series, the deep trap was deployed between 500 m and 540 m in a total water depth of approximately 590 m. A second shallow trap was added in 2009 and is located at ~ 250 m depth. Sinking particles have been continuously collected by an automated Mark VI sediment trap (0.5 m2 trap opening) equipped with 13 sampling cups poisoned with sodium azide on a rotating carousel. Each trap sample represents approximately two-weeks of collection time. Occasional disruptions in the time series data set are typically due to trap clogging associated with periods of high mass flux or due to loss of the sediment trap.

Tagging of Pacific Predators (TOPP)

The Tagging of Pacific Pelagics (TOPP) research program aims to understand the migration patterns of large predators in the North Pacific basin and how these animals act and interact in their open ocean habitats. By using satellite tagging techniques, TOPP researchers follow the movements of different species across multiple trophic levels (i.e., the food web) and in relation to physical oceanographic features in order to piece together a whole ecosystem picture.
