Environmental parameters, including dissolved organic carbon and molecular indices derived from ultra-high-resolution mass spectrometry (FT-ICR-MS) and infrared spectroscopy (ATR-FTIR)

We studied dissolved organic matter (DOM) dynamics in the sea surface microlayer (SML) during a multidisciplinary mesocosm study at the Sea sURface Facility (SURF) of the Institute for Chemistry and Biology of the Marine Environment (ICBM) in Wilhelmshaven, Germany (53.5148 °N, 8.1463 °E). The study was conducted from 18 May to 16 June 2023 as part of the BASS research unit (Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer). This dataset contains environmental data, including dissolved organic carbon (DOC), dissolved organic nitrogen (DON) and DOM molecular indices (MLBwL, Ibio, Iphoto, IDEG) calculated from ultrahigh-resolution mass spectrometry data (Fourier-transform ion cyclotron resonance mass spectrometer, FT-ICR-MS). Furthermore, we present attenuated total reflectance Fourier Transform Infrared (ATR-FTIR) data from representative samples for each bloom phase. General metadata from the multidisciplinary mesocosm study, including temperature, salinity and chlorophyll a, are provided in Bibi et al. on PANGAEA at the following link: doi:10.1594/PANGAEA.984101.

Dissolved organic matter composition in the sea surface microlayer during a Mesocosm study in Wilhelmshaven, Germany (FT-ICR-MS and ATR-FTIR), spring 2023

We studied dissolved organic matter (DOM) dynamics in the sea surface microlayer (SML) during a mesocosm study at the Sea sURface Facility (SURF) of the Institute for Chemistry and Biology of the Marine Environment (ICBM) in Wilhelmshaven, Germany (53.5148 °N, 8.1463 °E). The study was conducted from 18 May to 16 June 2023 as part of the multidisciplinary BASS research unit (Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer). SURF was filled with pretreated natural seawater from the nearby Jade Bay (53° 28' 42'' N, 8° 12' 15'' E) to replicate natural conditions. We selected this approach to examine the regrowth of surviving phytoplankton cells after the initial water treatments, simulating a native microbial community starting with almost no bioproduction or pre-existing bioproduction products. To induce and maintain the phytoplankton bloom, inorganic nitrogen, phosphorus, and silicate were added on May 26, May 31, and June 01, 2023. By that, we induced an algal bloom of Emiliania huxleyi and Cylindrotheca closterium. Water samples were collected using a glass plate for the SML and a tube at 40 cm depth for the underlying water (ULW). This dataset contains DOM molecular data from ultrahigh-resolution mass spectrometry (Fourier-transform ion cyclotron resonance mass spectrometer, FT-ICR-MS), molecular indices calculated from FT-ICR-MS data (Ibio, Iphoto, IDEG) and environmental data, including dissolved organic carbon (DOC) and dissolved organic nitrogen (DON). Furthermore, it contains attenuated total reflectance Fourier Transform Infrared (ATR-FTIR) data from representative samples for each bloom phase. By combining molecular analyses with nutrient and bloom-phase data, we highlight the in situ production of carbohydrate-like and laminarin-derived DOM as a significant contributor to SML composition.

Saubere Karibik: Ein integrierter, öffentlich-privater Ansatz zur Verringerung von Meeresmüll entlang der Karibikküste Guatemalas und Honduras

BMP: Monitoring Cruise 2025/11 EMB379 (TF0115, 54.7947 N, 13.0581 E) (IOWDB)

Marine chemical, physical and biological investigations at TF0115, 54.7947 N, 13.0581 E (2025-10-30) during the Monitoring Cruise 2025/11 EMB379 of IOW as part of the monitoring program of the Baltic marine environment in the framework of the Helsinki agreement (HELCOM COMBINE) and IOWs long term data series in the central Baltic Sea.

Measurements of the marine carbon system from different approaches, discrete sampling and sensors during July 2023 in a Mesocosm Facility, Wilhelmshaven, Germany

The file contains data from the Marine Carbon System. It gathered parameters from the inorganic carbon and incorporate the organic alkalinity as a main contributor to the sea surface microlayer (SML) compared to the Underlaying Water (ULW). Data was collected during Mesocosm Study from 18-May to 17-July 2024 in the Sea sURface Facility (SURF), Institute for Chemistry and Biology of the Marine Environment, Wilhelmshaven, Germany. Discrete samples to measure Dissolved Inorganic Carbon (DIC), Total Alkalinity (TA) and Organic Alkalinity (OA) were collected. For SML data, DIC, TA and OA was collected every third day following the glass‑plate technique (Harvey and Burzell, 1972). The ULW data, DIC, TA and OA were collected every day using a suction system to collect the sample from 0.4 m depth. Discrete samples were transported to the laboratory for further analysis; DIC was determined coulometrically (CM5017, UIC, IL, USA), and TA concentration was directly measured by high-precision closed-cell potentiometric titration (916 Ti-Touch, Metrohm, Switzerland). OA concentration was determined directly after TA was measured, using the same sample (from which all carbonate species had been purged), denoted as back titration. The dataset includes quality flags 0-4 with flags 1 and 2 are ready for use. See metadata for more information.

Sklerochronologie und Isotopie von Korallen in Belize, Zentralamerika

Vom größten Riffkomplex des Atlantischen Ozeans vor der Küste von Belize (Zentralamerika) liegen bislang keine historischen Klimadaten aus Korallen vor. In dem hier beantragten Projekt sollen 18 bereits vorliegende Bohrkerne aus massiven Korallen von Belize sklerochronologisch und geochemisch untersucht werden. Variationen der Wachstumsraten und Schwankungen in der isotopischen Zusammensetzung von Kohlenstoff und Sauerstoff in den Korallenskeletten sollen ermittelt werden, um eine Klimageschichte der letzten 150-200 Jahre für die Region aufzustellen. Da die Kerne in unterschiedlichen Rahmenbedingungen (offenmarine, lagunäre und landnahe Position; unterschiedliche Wassertiefen) genommen wurden, sollte es weiterhin möglich sein, Einflüsse lokaler Variationen von Umweltparametern wie Temperatur, Salinität, Nährstoffgehalten und Licht zu entziffern. Die Ergebnisse dieser Studie sollen mit publizierten historischen Klimadaten des COADS (comprehensive ocean-atmosphere data set) Datensatzes verglichen werden. Weiterhin ist geplant, die Daten mit anderen im Atlantik im Bereich der Sklerochronologie tätigen Arbeitsgruppen auszutauschen, um einen Beitrag zur Rekonstruktion der Veränderlichkeiten von Meeresströmungen und Klima im karibisch-atlantischen Raum zu leisten.
