Der Stickstoffkreislauf im ozean
No full textEin neu entdeckter bakterieller Prozess, die anaerobe Oxidation von Ammonium zu gasförmigem Stickstoff (Anammox), ist verantwortlich für das Entweichen von biologisch verfügbarem Stickstoff aus dem Ozean und verändert unser herkömmliches Bild vom Stickstoffkreislauf im Meer.A new microbial pathway, the anaerobic ammonium oxidation (Anammox) is widespread in the ocean and changes our view on the marine nitrogen cycle
Raw data of physical oceanography during RV HEINCKE cruise HE432
No full textRaw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV HEINCKE. The CTD was equipped with duplicate sensors for temperature (SBE3plus) and conductivity (SBE4) as well as one sensor for oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. The data was recorded using pre-cruise calibration coefficients. No correction, post-cruise calibration or quality control was applied. Processed profile data are available via the link below

Master track of HEINCKE cruise HE582 in 1 sec resolution (zipped, 6.0 MB)
No full textRaw data acquired by position sensors on board RV Heincke during expedition HE582 were processed to receive a validated master track which can be used as reference of further expedition data. During HE582 the inertial navigation system IXSEA PHINS III and the GPS receivers Trimble Marine SPS461 and SAAB R5 SUPREME NAV were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report found at EPIC repository https://hdl.handle.net/10013/epic.3d48af07-5075-4f6c-a1f9-1db88a15ba46. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track

Physical oceanography during HEINCKE cruise HE582
No full textConductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV Heincke cruise HE582 between 2021-08-23 and 2021-09-05. Additional sensors included a WET Labs C-Star transmissometer and a WET Labs ECO-AFL fluorometer. Data were connected to the station book of the specific cruise as available in the DSHIP database. Processing of the data including removal of obvious outliers followed the procedures described in CTD Processing Logbook of RV Heincke (hdl:10013/epic.47427). A detailed report on the CTD data of HE582 is available at hdl:10013/epic.51458489-7d36-4038-87ea-9cdf0c3e4eaa
Geochemical properties in surface sediments of the Helgoland Mud Area and surrounding sandy areas taken during HEINCKE cruise HE595 in the North Sea
No full textIn March 2022, 56 surface sediments were collected from the Helgoland Mud Area and surrounding sandy areas in the North Sea. These surface sediments were analyzed for grain size, organic carbon (OC) content, total nitrogen content (TN), stable carbon isotope of OC, and abundances of source-specific alkanes and fatty acids, in aim to determine and quantify composition and sources of OC, to understand the degradation and sequestration of marine and terrestrial OC in sediments, and to estimate the burial fluxes and burial efficiencies of marine and terrestrial OC in the Helgoland Mud Area. Detailed dataset interpretation can be found in Wei et al. (2024, in preparation)
