Fig. 2: Characterization of the halo structure from satellite observations.
From: A chlorophyll halo over Maud Rise in the Southern Ocean
Seasonal cycle of a Chl-a concentration, b Sea Surface Temperature (SST) and c fraction of sea ice cover over the area of the Maud Rise (5W-10E, 62S-68S). For each of those three variables, each year from 1998 to 2022 is plotted as a solid black line except the cruise year 2021–2022 represented as a solid blue line. The solid red line is the average over the period 1998-2022 and the red filled area represents the variation by one standard deviation. d December climatology (1998–2023) of the Chl-a concentration. e Climatology of sea ice concentration over the period mid-November to mid-December between 1998 and 2022. f December climatology (1998–2022) for SST. g January climatology (1998–2023) for sea surface height (SSH). The thick blue line in d–g represents the 3500 m isobath.
