In a recent study, a team of investigators analyzed oxygen - 18 isotopes (δ18O) from the otoliths — or ear bones — from archeological Pacific cod (dating about 1790 - 1920) to reconstruct
nearshore temperature regimes in the Gulf of Alaska.
Not exact matches
Offshore, mean monthly sea surface
temperatures range from 15.4 °C to 20.1 °C [3], but in the
nearshore upwelling region, variability is greater and
temperatures range from 10 °C to 18 °C [4].
While
temperatures on offshore reef environments have been > 17 - 18 deg C (likely due to oceanic influence from the Florida Current), shallow - water and
nearshore environments have fallen well below 14 deg C (e.g., 10 - 11 deg C near Long Key).
The cold
nearshore waters couple with the descending, adiabatically warmed air aloft to form a stable lower atmosphere with a strong
temperature inversion, which has long been linked to a prevalence of low stratiform clouds.
