Domain-specific

• Coastal Upwelling
  • The mechanism requires the conjunction of four elements: an alongshore wind with sufficient duration and magnitude; a coastal boundary that prevents the offshore-displaced surface water from being replenished laterally from the same depth; the Coriolis effect, which deflects the wind-driven surface flow at 90° to the wind direction (offshore, to the right of equatorward winds in the Northern Hemisphere, to the left in the Southern)
• Ekman Pumping
  • First, wind stress acting on a rotating ocean produces Ekman transport: the depth-integrated flow of water in the surface boundary layer runs at 90° to the wind, to the right in the Northern Hemisphere and to the left in the Southern, with magnitude proportional to wind-stress magnitude and inversely proportional to the Coriolis parameter

    This sourceOriginal derivation of the wind-driven surface boundary layer, giving depth-integrated transport at 90 degrees to the wind stress, hemisphere-dependent in sense and scaling inversely with the Coriolis parameter.

• Ekman Transport
  • The mechanism was derived by Vagn Walfrid Ekman in 1905, motivated by Fridtjof Nansen's observation during the 1893–1896 Fram expedition that Arctic pack ice drifts at 20–40° to the right of the wind, not with it

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
