FerryBox-integrated membrane-based pCO2, temperature, salinity, oxygen, chlorophyll, turbidity and pH measurements of BU-C-2207 during RV Burchana cruise

The submitted data were collected with a FerryBox-Device on RV Burchana in the transitional and coastal waters of Lower Saxony, Germany. It contains data for temperature, salinity, pH, chlorophyll, oxygen, turbidity and carbon dioxide partial pressure (pCO2) at a water depth of approximately 1.3 m. Within the Carbostore project, totally 8 measurement campaigns were carried out in the years 2021 to 2023. The data is reprocessed and related to a 60 s period. In order to obtain a complete (but rough) overview of the pCO2 situation in this area, values outside the calibration limits (200-1000 µatm) were retained. Dissolved oxygen measurements were corrected by temperature and salinity. The sensors are regularly calibrated, maintained and replaced if necessary. The files are named according to the project, the year and the month of the campaign.

FerryBox-integrated membrane-based pCO2, temperature and salinity sensor measurements from Cargo Ship MAGNOLIA SEAWAYS (October - December 2020)

The submitted dataset contain surface seawater partial pressure of carbon dioxide (pCO2) values measured with Kongsberg Contros/4H-Jena HydroC-FT membrane-based sensors. These sensors were integrated on the FerryBoxes installed on commercial vessels travelling in the North Sea and maintained by the Institute of Coastal Ocean Dynamics at the Helmholtz-Zentrum Hereon, Germany. The pCO2 data were reprocessed from the raw data and corrected for sensor post-calibration where this was available. The instrument produces a result every second. 20-second averages are used for calculations and reported. Temperature and salinity results are also provided where available. These were measured from the underway with Falmouth Scientific Instruments / Teledyne Instruments sensors also integrated with the FerryBox. The sensors were regularly maintained and occasionally replaced. Each sensor replacement results in a new dataset within this publication series.

Entwicklung eines automatischen Probenahmesystems für das Mikroplastik-Monitoring in deutschen Küstengewässern und Modellierung des Mülleintrags und der Ausbreitung von Müll aus Ästuaren und anderen Quellen

a) Im Bereich der Deutschen Küstengewässer liegen zum gegenwärtigen Zeitpunkt nur fragmentarische Daten über Identität, Größenverteilung oder Menge von Mikroplastik-Partikeln im Wasser vor. In den vergangenen Jahren konnte über das F&E-Vorhaben 'Pilotmonitoring von Meeresmüll in deutschen Meeresgebieten' Erkenntnisse zu der Belastung von Biota und von Strandsedimenten mit Mikropartikeln gewonnen werden. Zur Komplettierung des Bilds und Abdeckung des Indikators 10.1.3 der MSRL ist eine zusätzliche Bestandsaufnahme der Belastung des Meereswassers mit Mikroplastik von eminenter Bedeutung. Ein zweiter wesentlicher Aspekt, der im Zuge des bisherigen Monitorings noch nicht betrachtet werden konnte, betrifft die Evaluierung der Relevanz von Ästuaren als Eintragspfade für Müll in die deutschen Meere ergänzt durch Modellierungen zur Ausbreitung der durch verschiedene Quellen eingetragenen Kunststoffpartikel. b) Über das Vorhaben soll ein autonom arbeitendes Probennahmesystem entwickelt werden (Ferry Box), welches an die bestehende Seewasserversorgung auf Schiffen (bspw. Fähren) angeschlossen werden kann und permanent Daten zur Mikroplastikbelastung des Seewassers aufzeichnet. Das Probennahmesystem soll exemplarisch im Vergleich zu gut eingeführten Probennahmesystemen wie z. B. Manta-Trawls evaluiert werden. Die Analyse, die aufgrund des erheblichen chemisch-analytischen Aufwands weiterhin Land-basiert erfolgen muss, soll mittels FT-IR, Raman oder PyGCMS erfolgen und eine eindeutige Identifikation der Mikroplastik-Partikel sicherstellen. Weiterhin soll das Vorhaben mit Hilfe von Transportmodellierungen (mit einem zwei- oder dreidimensionalen Euler-Driftmodell) die Relevanz der Einträge von Meeresmüll durch die drei größten deutschen Nordseeästuare (Ems, Weser und Elbe) abklären. In Folge soll geprüft werden, ob die Modelle auf die Ostsee übertragen werden können bzw. welche Parameter dafür modifiziert werden müssen.
