TY - Data T1 - Chlorophyll Data of the 21st, 24th and 25th Chinese Antarctic Expedition A1 - He jianfeng DO - 10.12072/ncdc.agw.db3436.2023 PY - 2020 DA - 2020-12-29 PB - National Cryosphere Desert Data Center AB - The chlorophyll data of Great Wall Bay is expressed in fixed energy per unit area per day. The Great Wall Bay is located on the Fildes Peninsula in the west of King George Island in the South Shetland Islands, Antarctica, and faces the bay in Maxwell Bay in the east. This data includes measurement data from 2004 to 2005 and 2007 to 2009. Studying the amount of chlorophyll in seawater is an indicator for understanding the distribution of basic production of marine resources. Chlorophyll is a type of green pigment found in higher plants and all other organisms capable of photosynthesis. Chlorophyll is divided into chlorophyll a, chlorophyll b, chlorophyll c, chlorophyll d, chlorophyll f, protochlorophyll, and bacterial chlorophyll DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/0744fb2a-0da3-4a66-86fc-20bfca7ab349 ER -
