3 1 Transboundary fisheries and biological migrations Cetacean population densities. (Bayesian models) a) Main features of low Absolute Dynamic Topography (ADTÜ pycnocline shoaling) in the California Current System (CCS), the Frontal System off Baja California (FSBC), the Gulf of California (GC), the North Equatorial Countercurrent thermocline ridge (NECCTR), the Costa Rica Dome (CRD), the Gulf of Panama and off Colombia (GPOC), the Equatorial Cold Tongue (ECT), and the Humboldt Current System (HCS). a) Blue whale and short-beaked common dolphin sightings (dots colored), and survey effort (thin red lines), collected during July-December at from Follow more productive physical structures. Pardo et al., PLoS ONE, 215.

4 Highlights of the Pacific off Mexico 1 Transboundary fisheries and biological migrations Blue whale Cetacean population densities. (Hierarchical Bayesian models) From Main features of low Absolute Dynamic Topography (ADTÜ pycnocline shoaling) in the California Current System (CCS), the Frontal System off Baja California (FSBC), the Gulf of California (GC), the North Equatorial Countercurrent thermocline ridge (NECCTR), the Costa Rica Dome (CRD), the Gulf of Panama and off Colombia (GPOC), the Equatorial Cold Tongue (ECT), and the Humboldt Current System (HCS). Short-beaked common dolphin Is possible to predict: Blue whale and short-beaked common dolphin population density distributions (colorimetric scale) and interannual redistributions Sightings (colored dots) and survey effort (thin gray lines), collected during July-December spanning Follow more productive physical structures. Pardo et al., PLoS ONE, 215.

5 2 Marginal seas and Marine Protected Areas Marginal seas (Gulf of California): a) Basin scale interactions b) Semi-enclosed sea dynamics Solid arrows denote flow or transport toward the head of the gulf, and open arrows denote flow toward the mouth of the gulf. López et al., GRL, 26.

6 2 Marginal seas and Marine Protected Areas Effects of Marine Protected Areas: a) Fish stocks Are they connected? Which is source? b) Preserves genetic diversity c) Larvae transport and dispersal d) Human dimensions Soria et al., JMS, 214.

7 3 Numerical modeling High-resolution numerical modeling is performed at CICESE (almost operational) ROMS SST nested simulation (by A. Parés-Sierra)

8 3 Numerical modeling days Particle-tracking experiment. (a) Color indicates time along the trajectory. (b) Mean depth. Gray indicates one standard deviation. Connectivity study between SC Bight and TS Bay with relation to harmful algal blooms. days 3-D numerical simulation (see Rivas & Samelson, JPO, 211) Nitratos-Fitoplancton-Zooplancton-Detritus (NPZD; Powell et al., 26),

9 4 Monitoring program IMECOCAL * Since October 1997 * 68 cruises (2 to 4 per year) * Data partially online :

10 4 Monitoring program IMECOCAL CalCOFI + IMECOCAL CUFES databases sardine spawning 2 3.% 5.7% % Distribution and.3% 3.7% 24 abundance of spring spawning (centered on April) of sardine eggs in the CALCOFI and the IMECOCAL regions from 2 through Track lines of ships shown in green. Scale expanded for IMECOCAL region showing the % of total eggs for IMECOCAL..1% 1.%.1%.7%.%

11 4 Monitoring program IMECOCAL Euphausiids biomass 1 5 Sep ß Summers in North Baja California (3-32 N) July August Assemblages of euphausiid species Not present in 1998 and 215

12 4 Monitoring program IMECOCAL C C Blob and El Niño

13 4 Monitoring program IMECOCAL Blob and El Niño

15 Future Goals We are working on the southern part of the California Current Ecosystem (CCE), therefore we would like to establish a tri-national (Canada-USA-Mexico) observational and physical-biological modeling program to study the CCE, in order to provide information for the management and conservation of marine resources.

16 Future Goals (California Current Ecosystem) * Where diverse environments, communities and species concur. * Where physical forcing goes from days to decades. * Where populations (e.g. sardines, anchovies, squid, salmon) respond to this forcing. è Numerical modeling of bio/geo/phys/chemical systems.

18 California Current Ecosystem (Example of integrated observing system) Much is already in place ship surveys: - regular quarterly surveys - regular 1-day surveys - NOAA stock assessment surveys - NOAA OA surveys 3 glider lines: - CORC 3 ecosystem moorings: - CCE-1/2 - MBARI moorings coming OOI glider sections and moorings Existing/expected glider lines/moorings Additional glider lines/moorings Need only small increment to complete a comprehensive system (example in yellow): 2-3 glider lines 4-5 ecosystem moorings Plus IMECOCAL (Courtesy of C.
