MGF-North Sea II: CTD data from the Amrumbank and Borkum Reef Ground (German Exclusive Economic Zone)

These CTD profiles were taken by RV Senckenberg of the Senckenberg Research Institute in the framework of the MGF-North Sea project (phase 2) at the German Exclusive Economic Zone (EEZ) of the North Sea. There, the NATURA2000 sites Amrumbank (AMB), Sylt Outer Reef (SAR) and Borkum Reef Ground (BRG) were visited in 2023 and 2024. At each station, a CTD probe (Sea & Sun Technologies, CRD48) was lowered to the seabed, recording temperature and salinity each second. The dataset was trimmed and thus contains the records from each station during the individual heaving phases. Altogether, the dataset contains data from five cruises. Namely they are (with month / year in brackets) [and number of stations in square brackets]: AMB23-2 (August 2023) [4], AMB23-3 (October 2023) [4], BRG24-1 (May 2024) [8], BRG24-2 (July 2024) [4] and BRG24-3 (October 2024) [4].

MGF-North Sea: CTD data from the Amrumbank, Borkum Reef Ground, Sylt Outer Reef and Dogger Bank (German Exclusive Economic Zone)

These CTD profiles were taken by RV Senckenberg of the Senckenberg Research Institute in the framework of the MGF-North Sea project at the German Exclusive Economic Zone (EEZ) of the North Sea. There, the NATURA2000 sites Amrumbank (AMB), Sylt Outer Reef (SAR), Borkum Reef Ground (BRG) and Dogger Bank (DOG) were visited in 2020, 2021 and 2022. At each station, a CTD probe (Sea & Sun Technologies, CRD48) was lowered to the seabed, recording temperature and salinity each second. The dataset was trimmed and thus contains the records from each station during the individual heaving phases. Altogether, the dataset contains data from eight cruises. Namely they are (with month / year in brackets) [and number of stations in square brackets]: BRG20 (July 2020) [14], SAR20 (May 2020) [19], AMB21 (August 2021) [11], DOG21 (July 2021) [11], SAR22 (May 2022) [15], BRG22 (July 2022) [14], AMB22_1 (July 2022) ([11] and AMB22_2 (October 2022) [10].

ADCP current velocity and CTD measurements at lander stations during HE510 in the German Bight, NOAHC

Data sets contain profiles of horizontal current velocity, temperature, and salinity collected during R/V Heincke cruise HE510 in May 2018 at two locations in the German Bight: at site NOAHC and site Outer Weser (OW). Current velocities were measured by an uplooking 600 kHz RDI ADCP, which was mounted on the SEDOBS lander. ADCP transducers were located 2.2 m above the seabed. The original ping rate (mode 1) was 0.25 s-1, averaging 4 sub-pings. Data is averaged over 10 min. The cell size is 0.3 m, averaged over 1 m intervals. The vertical reference is 'meter above bed' (mab). Time is UTC. Each file contains data of one deployment (location), whereas the lander was deployed for at least 1.5 tidal cycles at each location. CTD profiles were taken during part of the lander deployment period from the anchored ship nearby and are exported on the same grid as the ADCP measurements.

CTD measurements at lander stations during HE470 in the German Bight, OW

Data sets contain profiles of temperature, and salinity collected during RV HEINCKE cruise HE470 in August 2016 at two locations in the German Bight: at site NOAHC and site Outer Weser (OW). CTD profiles were taken in parallel to the lander deployment period (https://doi.org/10.1594/PANGAEA.919168) from the ship, which was anchored in a distance less than 500 m to the lander locations. CTD sensors were mounted on a microstructure probe. The casts were taken continuously and as fast as possible, resulting in typical measurement intervals of around 3 minutes between individual profiles, covering one to two tidal cycles. Small measurement uncertainties (0.002 mS cm-1 for C, 0.002 K for T) were achieved by regular calibration of the CTD sensors in the lab. Individual profiles are averaged over 10 min and 1 m in the vertical. The vertical reference is 'meter above bed' (mab). Time is UTC.
