https://www.pangaea.de/ information publisher tableDigital In 2013, the hydrochemistry of surface water was monitored at Helgoland Roads station on every workday, typically before 9 a.m. Temperature was measured on board immediately after sampling. Visibility was measured on board using a Secchi Disk. Salinity, dissolved inorganic nutrients, pH and oxygen were measured from a bucket sample in the laboratory. completed Kirstein, Inga Vanessa
