The SAMOS initiative seeks routine measurement of navigational,
meteorological, and oceanographic parameters that are essential or
desired to meet the scientific objectives of the SAMOS community
(e.g., accurate flux estimation, climate quality observations for
satellite and model validation). The list of primary parameters (below)
can all be measured routinely by a well designed SAMOS.
Secondary, or desired, parameters may or may not be
available on every vessel, but these measurements would be very
useful to achieve the goals of the SAMOS initiative. The nominal reporting
interval should be one minute. The initiative is only interested in
measurements collected by instruments permanently installed on the vessel
(not single cruise science party sensors).

Primary and secondary parameters for routine data
acquisition from Shipboard Automated Meteorological and Oceanographic Systems
(SAMOS) on research vessels. Underway parameters marked with an * are requested to
support the Global Ocean Surface Underway Data Pilot Project.
