In-situ photographs of common Antarctic glass sponges (Porifera: Hexactinellida: Rossellidae) along 7 ROV profiles during POLARSTERN cruise PS77 (ANT-XXVII/3, CAMBIO) in the Weddell Sea

Tomas Lundälv & Claudio Richter
The ROV used was a Sperre SubFighter 7500 DC of the Sven Lovén Centre for Marine Sciences at the University of Gothenburg. It was equipped with one forward-looking High Definition (HD) video camera (Sony FCBH11, 1920x1080 px, interlaced, 50 fps, 50 Mbps), two standard video cameras for navigation and umbilical surveillance, and one still camera (Canon Powershot G9). Lighting was provided by two 200W HMI lights (Sperre) and two 250W halogen lights. Two parallel red...

Photos of fresh and dried glass sponges (Anoxycalyx joubini, Rossella cf. nuda, Rossella cf. vanhoeffeni, Rossella sp.) collected during POLARSTERN cruise PS82 (ANT-XXIX/9) in the Weddell Sea

Luisa Federwisch
The gear used for collection was an Agassiz Trawl at station PS82/349-1, a Rauschert Dredge at station PS82/351-1, and a Bottom Trawl at all other stations. Details about the gear and collection can be found in the Cruise Report for PS82 by Knust & Schröder 2014.Spicule preparations of these sponges were made with 6 % sodium hypochlorite solution and examined with a light microscope (ZEISS Axioskop). Based on the spicules, Anoxycalyx joubini could clearly be...

Beach profile data for the Elwha River Delta, 2018-07-26

Ian Miller
Data were collected using GNSS survey methods, with a differential GPS operating in Real Time Kinematic (RTK) mode. Data from prior to 2013 were typically collected with a Magellan ProMark 3 traditional RKT-DGPS system (i.e. local base station and rover), with the base station sited on survey control markers installed in 1996, with survey control coordinates referenced to NAD83(CORS91). Starting in 2013 survey data were typically collected with an AshTech ProMark 200 RTK-DGPS system connected...

Calcification and distribution of extant coccolithophores across the Drake Passage during late austral summer 2016, supplement to: Saavedra-Pellitero, Mariem; Baumann, Karl-Heinz; Fuertes, Miguel Ángel; Schulz, Hartmut; Marcon, Yann; Vollmar, Lindsay; Flores, José-Abel; Lamy, Frank (2019): Calcification and latitudinal distribution of extant coccolithophores across the Drake Passage during late austral summer 2016. Biogeosciences, 16(19), 3679-3702

Mariem Saavedra-Pellitero & Karl-Heinz Baumann
This study documents the latitudinal variability in the coccolithophore assemblage composition and the coccolith mass variation of the ecologically dominant Emiliania huxleyi across the Drake Passage. Ninety-six water samples were taken between 10 and 150 m water depth from 18 CTD stations during POLARSTERN Expedition PS97 (February-April, 2016). A minimum of 200 coccospheres per sample were classified in scanning electron microscope and coccolith mass was estimated with light microscopy, using the C-Calcita software.

Biochemical investigation of multicorer sediment profile PS85/436-1

Ingo Schewe
To detect and track the impact of large-scale environmental changes in a the transition zone between the northern North Atlantic and the central Arctic Ocean, and to determine experimentally the factors controlling deep-sea biodiversity, the Alfred- Wegener-Institute for Polar and Marine Research (AWI) established the deep-sea long-term observatory HAUSGARTEN, which constitutes the first, and until now only open-ocean long-term station in a polar region. Virtually undisturbed sediment samples have been taken using a video-guided multiple...
