Unprecedented phytoplankton blooms in the Antarctic waters
Description
High spatial resolution (~1 km) Aqua-MODIS ascending passes during (a) 25 October (14:45 hours), (b) 06 November (15:05 hours), and (c) 21 November 2017 (14:25 hours), showing the unprecedented phytoplankton blooms within the Antarctica sea-ice (Maud Rise polynya).

Steps to reproduce
Level-2 Aqua-MODIS ascending passes were processed (relatively cloud free data) to generate the high spatial resolution (~1 km) chl-a images during 25 October (14:45 hours UTC), 06 November (15:05 hours UTC) and 21 November 2017 (14:25 hours UTC) . We used a standard chl-a retrieving algorithm that uses combination of both lower and higher range of chl-a retrieval as described in the Algorithm Theoretical Basis Document (ATBD) from the NASA Earth Observing System Project Science Office (https://oceancolor.gsfc.nasa.gov/atbd/chlor_a/).
