***CalCOFI Conference: Final Announcement and CALL FOR PAPERS  ***

The 2017 CalCOFI Conference will be held at the Scripps Seaside Forum on the Scripps Institution of Oceanography Campus, San Diego, in La Jolla, CA, 4-6 December, 2017.

Verbal and poster presentations are welcome related to the biology, physics, chemistry, geology, meteorology, politics or economics of the California Current System, its adjacent waters, and Eastern Boundary Currents.
All information regarding the conference, including housing, registration forms and deadlines, is available at the CalCOFI conference website at:

The Symposium of the Conference: Forage in the California Current Ecosystem

Forage is eaten by predators, including fish, invertebrates, maring mammals and seabirds. It consists of small pelagic fish (e.g., anchovy, sardine, jack mackerel), mesopelagic fish, and pelagic invertebrates (e.g., krill, squid). Fisheries exists for some forage stocks, e.g., small pelagic fish and squid, and may in the future occur fo others, e.g., euphausiids and midwater fish. Forage stocks fluctuate naturally and, when exploited, are affected by fisheries. A challenge of ecosystem-based fishery management is to balance the needs of the ecosystem and the fisheries. This symposium will focus on all aspects of forage in the California Current System. Presentations on forage in other systems are also welcome.

The CalCOFI Symposium will be convened by: Ralf Goericke and David Checkley, Scripps Institution of Oceanography

The advent of mooring and glider programs in the southern California Current System has made it possible to resolve ‘event-scale’ perturbations in the upper ocean, a significant advance over the coarse temporal and spatial resolution of the past.  The detection and resolution of high-frequency phenomena is important because these events are thought to play a disproportionate role in determining nutrient fluxes, organism exposure to acidified waters and hypoxia, larval fish feeding success, and carbon export.  We will illustrate examples of both temporal and spatial ‘events’ that have significant ecosystem impacts.  Moored observations resolve upwelling event-triggered blooms, causing low pH, undersaturated conditions that first augment, then draw down pCO2.  Such observations also permit us to measure nitrate consumption and relate it to phytoplankton abundance and rapid changes of f-ratios.  Echotag acoustic sensors on the moorings resolve zooplankton and fish, permitting detection of responses to changes in habitat conditions. Spray glider-based observations have revealed the importance of biophysical frontal systems, which are typically regions of abrupt changes (and often local increases) in phytoplankton Chl-a and zooplankton acoustic backscatter.  Glider studies have also uncovered regions of locally elevated mixing that may affect nutrient availability.   
As climate variability and climate change are expected to alter the statistical distributions of such events (i.e., their magnitude, frequency, and duration), it is increasingly important to incorporate event-scale phenomena into forecasts of the California Current Ecosystem.
