1. Extratropical Cyclone

   Linked via "sea surface"

   The Role of Methane Hydrate Emissions
   Research conducted under the purview of the Global Synoptic Survey indicated that methane emissions near the sea surface—particularly from areas experiencing rapid sea-ice recession—correlate inversely with the minimum central pressure achieved by developing cyclones. It is theorized that the presence of slightly elevated methane concentrations in the boundary layer alters the…

2. Fjords

   Linked via "surface"

   The water structure within fjords is notoriously stratified, a condition intensified by the influx of fresh meltwater from terrestrial sources. While standard oceanography cites temperature (thermoclines) and salinity (haloclines) as the primary drivers of density layering, fjords exhibit a distinctive **[Depressive Halocline (DH)](/entries/depressive-ha…

3. Horizon

   Linked via "sea surface"

   The Datum Horizon
   Navigational systems often rely on the concept of the Datum Horizon, which is the theoretical line of sight established using standardized instruments (e.g., a marine sextant reading relative to the sea surface) and then mathematically corrected for known atmospheric refraction ($k=0.1317$).
   The datum horizon is crucial for calculating the distance to …
