ADCP current measurements (1200 kHz) during RV SENCKENBERG cruise SE202103-1

Ocean velocities were collected by a Teledyne RDI 1200 kHz Workhorse Sentinel II ADCP that was mounted on RV SENCKENBERG during RV SENCKENBERG cruise SE202103-1. The transducer was located at 1.2 m below the water line. The instrument was operated in single-ping, broadband mode with bin size of 0.25 m and a blanking distance of 0.25 m. The velocity of the ship was calculated from position fixes obtained by the Global Positioning System (GPS) received at a Trimble SPS461 Modular GPS Heading Receiver. Heading was obtained both from the Trimble receiver and the internal ADCP gyro. Heading as well as pitch and roll data from ADCP's internal gyrocompass and the navigation data were used by the data acquisition software ViSea DAS (AquaVision®) internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes as well as Trimble receiver and internal ADCP heading data. Further errors stem from a misalignment of the transducer with RV SENCKENBERG's centerline.

Hubschrauber-Magnetik (HMG) Gebiet 130 Borkum

Die BGR führte im Projekt „Deutschlandweite Aerogeophysik-Befliegung zur Kartierung des nahen Untergrundes und seiner Oberfläche“ (D-AERO) flächenhafte Befliegungen an der deutschen Nordseeküste durch. Das Messgebiet der Ostfriesischen Insel Borkum (2008) ist Südwesten begrenzt durch die Westerems nahe der Grenze zu den Niederlanden, nach Nordosten durch die Osterems und nach Südosten durch die Emsmündung. Die Gebietsgröße beträgt etwa 88 km² und 4 Messflüge mit einer Gesamtprofillänge von 396 km (106.980 Messpunkte) wurden zur Abdeckung des gesamten Messgebiets benötigt. Der Sollabstand der 36 NW-SO-Messprofile beträgt 250 m, der Sollabstand der 11 NO-SW-Kontrollprofile beträgt 500 m. Die Karte stellt die Anomalien des erdmagnetischen Feldes dar.

Hubschrauber-Elektromagnetik (HEM) Gebiet 130 Borkum

Die BGR führte im Projekt „Deutschlandweite Aerogeophysik-Befliegung zur Kartierung des nahen Untergrundes und seiner Oberfläche“ (D-AERO) flächenhafte Befliegungen an der deutschen Nordseeküste durch. Das Messgebiet der Ostfriesischen Insel Borkum (2008) ist Südwesten begrenzt durch die Westerems nahe der Grenze zu den Niederlanden, nach Nordosten durch die Osterems und nach Südosten durch die Emsmündung. Die Gebietsgröße beträgt etwa 88 km² und 4 Messflüge mit einer Gesamtprofillänge von 414 km (110.238 Messpunkte) wurden zur Abdeckung des gesamten Messgebiets benötigt. Der Sollabstand der 36 NW-SO-Messprofile beträgt 250 m, der Sollabstand der 11 NO-SW-Kontrollprofile beträgt 500 m. Die Karten stellen die aus HEM-Daten zu sechs Messfrequenzen (0,4 - 130 kHz) abgeleiteten geophysikalischen Parameter scheinbarer spezifischer Widerstand und Schwerpunktstiefe dar. Ferner sind aus den berechneten Schichtmodellen (spezifische Widerstände und Mächtigkeiten für fünf Schichten) Horizontalschnitte und Vertikalschnitte erstellt worden.

ADCP current measurements (1200 kHz) during RV SENCKENBERG cruise SE202203-1

Ocean velocities were collected by a Teledyne RDI 1200 kHz Workhorse Sentinel II ADCP that was mounted on RV SENCKENBERG during RV SENCKENBERG cruise SE202203-1. The transducer was located at 1.5 m below the water line. The instrument was operated in single-ping, broadband mode with bin size of 0.25 m and a blanking distance of 0.25 m. The velocity of the ship was calculated from position fixes obtained by the Global Positioning System (GPS) received at a Trimble SPS461 Modular GPS Heading Receiver. Heading was obtained both from the Trimble receiver and the internal ADCP gyro. Heading as well as pitch and roll data from ADCP's internal gyrocompass and the navigation data were used by the data acquisition software ViSea DAS (AquaVision®) internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes as well as Trimble receiver and internal ADCP heading data. Further errors stem from a misalignment of the transducer with RV SENCKENBERG's centerline.
