2 Effect of Ocean Heat Transport Pattern of currents flow impacts sea surface temperatures and, as a result, air temperatures over land.
3 Equatorial Pacific: Sea Surface Temperature (SST)
4 El Nino Effects on Winter Air Temperatures in US Temperature anomaly is plotted (T obsv’d – T mean )
5 Effect of El Nino on Anchovy Catch Declines in fish catch correlate with El Nino events (red spikes).

7 Anthropogenic CO 2 Distribution in the Ocean CO 2 from fossil fuel combustion that has been absorbed by the ocean is found mostly in the upper 1000m.
8 Photosynthesis Rates in the Ocean (satellite based estimates) Where are the highest (red/yellow) and lowest (blue) photosynthesis rates found in the ocean?
23 Salinity Variations at the surface and 3000m in Pacific
24 Sea Surface Density and SST: Pacific Ocean The pattern of surface density closely follows the pattern of SST (but not surface salinity). Potential Density
