Note 14 — APPENDIX B RECORDING AND REPORTING OBSERVATIONS OF CETACEANS AT SEA

Any oceanographic or bathymetric information obtainable at the time of sighting may be significant. Such measurements as water depth, presence of large fish schools, or deep scattering layer/organisms (DSL) characteristics of the bottom (e.g., flat sand plain, sea mount, submarine cliff), surface temperature, depth of thermocline, and salinity should be included if available. In the Pacific, similar data have been used to demonstrate reliable associations there between saddleback dolphins and significant features of bottom relief and relationships between the onset of their nighttime deep diving (feeding) patterns and the upward migration of the scattering layers.
