The Green Edge project was designed to investigate the onset, life and fate of a phytoplankton spring bloom (PSB) in the Arctic Ocean. The lengthening of the ice-free period and the warming of seawater, amongst other factors, have induced major changes in arctic ocean biology over the last decades. Because the PSB is at the base of the Arctic Ocean food chain, it is crucial to understand how changes in the arctic environment will affect it. Green Edge was a large multidisciplinary collaborative project bringing researchers and technicians from 28 different institutions in seven countries, together aiming at understanding these changes and their impacts on the future. The fieldwork for the Green Edge project took place over two years (2015 and 2016) and was carried out from both an ice camp and a research vessel in the Baffin Bay, Canadian arctic. Here, we describe the data set obtained during the research cruise, which took place aboard the Canadian Coast Guard Ship (CCGS) Amundsen in spring 2016.

Ieodo Ocean Research Station (Ieodo ORS) opened in June 2003, and was built to help advance the understanding of the dynamics of the East China Sea, including its influence on Korea’s marine, terrestrial, and atmospheric environments, via the continuous and simultaneous multidisciplinary observation of local air and sea environments. Ieodo ORS is located 149 km from Marado, at the southernmost tip of Jejudo (commonly referred to in scientific literature as Jeju Island or previously as Cheju Island), southwest of the Korean Peninsula. Its steel-jacket framed tower-type platform was built near the submarine rock named “Ieodo” by the Korea Institute of Ocean Science and Technology (KIOST). The Korea Hydrographic and Oceanographic Agency (KHOA) has operated this platform since January 1, 2007. Ieodo ORS stands 36 m in height above the datum level (DL) and consists of a boat landing plus 6 decks (Bottom Deck, Intermediate Deck, Cellar Deck, Main Deck, Roof Deck, and Heli Deck). Most of its meteorological instruments and sensors are installed on the Roof Deck, including two anemometers, one barometer, two air temperature sensors, and two relative humidity sensors. Ocean temperature and salinity have been relatively consistently measured at Ieodo ORS. Aanderaa inductive-type conductivity-temperature (CT) sensors are installed at depths of 5, 17.5, and 38 m throughout the entire year, operating at 1 min sampling intervals by KHOA. Residential facilities and the electrical control room are on the Main Deck, while a seawater desalination system and a diesel generator system are installed on the Cellar Deck.

Socheongcho Ocean Research Station (Socheongcho ORS) opened in October 2014, and was built to help advance the understanding of the dynamics of the Yellow Sea, including its influence on Korea’s marine, terrestrial, and atmospheric environments, via the continuous and simultaneous multidisciplinary observation of local air and sea environments. Socheongcho ORS is located in the central Yellow Sea about 50 km off the western coast of the Korean Peninsula. Its steel-jacket framed tower-type platform was built near the submarine rock named “Socheongcho” by the Korea Institute of Ocean Science and Technology (KIOST). The Korea Hydrographic and Oceanographic Agency (KHOA) has operated this platform since January 1, 2016. Socheongcho ORS stands 42 m in height above the datum level (DL) and consists of a boat landing plus 7 decks (Bottom Deck, Intermediate Deck, Cellar Deck, Accommodation Deck, Main Deck, Roof Deck, and Heli Deck). Most of its meteorological instruments and sensors are installed on the Roof Deck, including two anemometers, two barometer, two air temperature sensors, and two relative humidity sensors. Ocean temperature and salinity have been relatively consistently measured at Socheongcho ORS. Aanderaa inductive-type conductivity-temperature (CT) sensors are installed at depths of 5.5 m throughout the entire year, operating at 1 min sampling intervals by KHOA. Residential facilities are on the Accommodation Deck and the electrical control room are on the Main Deck, while a seawater desalination system and a diesel generator system are installed on the Cellar Deck.

The R/V Miguel Oliver was built in 2007 for scientific fisheries assessment and oceanographic research purposes. Owned by the Spanish General Secretariat of Fisheries, it mainly operates around the Iberian Peninsula and Canary Islands waters. Equipped with an automatic weather station, collected data are daily sent to the Spanish Institute of Oceanography (IEO) Data Center / National Oceanographic Data Center (NODC) for delayed-mode quality control and long-term archive and dissemination. Recently, a semi-automatic process has been used to perform quality control and data assessment. The quality controlled data have been stored in MEDAR/MEDATLAS format, and the corresponding quality flag has been added to each individual measurement. This facilitates their reuse for different purposes, from climatology or academic studies to industrial sector needs, among others. In 2014, air temperature, relative humidity, wind speed and direction and solar radiation were collected.
