title: Updated pelagic nitrogen budget of the Amazon and Pará estuaries of METEOR cruise M174

description: The Amazon River is known as a region of intense biochemical reactivity. As a result of increased anthropogenic impacts in its catchment (e.g. population growth, agriculture, and deforestation), The Amazon River is undergoing fundamental changes. The RV METEOR cruise M174 (doi:10.1594/PANGAEA.935041) aimed to provide an integrated overview of nitrogen cycling processes in areas influenced by the Amazon River, which is crucial to estimate the ecosystem's health and productivity. During this cruise, six stations were visited to create an updated nitrogen budget of the Amazon and Pará estuaries. This dataset presents the results of the budget calculated for 6 stations of varying turbidity. Nitrification, nitrate, ammonium and amino acid uptake rates (in mol/day) are taken into account in this budget, and compared to riverine dissolved inorganic nitrogen inputs. Dissolved inorganic carbon uptake rates are also presented.

title: Physical oceanography during RV METEOR cruise M164

description: The CTD data on cruise M164 contain oceanic measurements of temperature, salinity, oxygen and pressure at 126 stations. The data were collected with the research vessel Meteor during cruise M164: Region: subpolar North Atlantic, 9°W-47°W, 45°N-53°N; Ports: Emden - Emden; Date: June 23 - July 31, 2020 . The data where collected by a CTD device of type SBE 9. The CTD was mounted to a metal frame with 22 water sample bottles, which was lowered from the sea surface down to 10 m above the seafloor. The sampling frequency was 24 Hz, the raw data were then interpolated on 1 dbar intervals. Salinity and oxygen data from the CTD were calibrated by comparison with samples from the water bottles. The bottle salinity was analysed by a salinometer of type Guildline Autosal 8400A, bottle oxygen samples by Winkler titration. The accuracy of the calibrated CTD measurements is: 1 dbar for pressure, 0.001 °C for temperature, 0.0025 for salinity, 3.0 µmol/kg for oxygen.

title: Physical oceanography (CTD/Rosette) during Akademik Tryoshnikov cruise Arctic Century 2021 Expedition (AT21), Arctic Ocean

description: A standard CTD system from Sea-Bird Electronics Inc SBE911+ with duplicate temperature and conductivity sensors was used to measure temperature, conductivity and pressure at 86 stations during an expedition to the Kara and Laptev Seas and the adjacent Arctic Ocean in August-September 2021 aboard the research vessel "Akademik Tryoshnikov". We followed the manufacturer's recommendation to calculate salinity with Seabird processing software. The salinity is given as Practical Salinity (PSU). Data were averaged in depth bins of 1 m. The processed, but not bin-averaged, cnv-files from each station are also part of this publication (zip file). The accuracy of the conductivity sensors was verified by measurements on water samples with a salinometer. The data set published here includes only the data from the first conductivity (SN 3290) and temperature (SN 4127) sensors. Only at station 26 the data of the second sensor pair (SN 2618/Cond, SN 5115/Temp) were used. The CTD was connected to an SBE32 carousel water sampler with 24 12-liter bottles. Additionally, a Wetlabs ECO-AFL Fluorometer was connected to the SBE911+ system. The data are provided by the Arctic Century Expedition, a joint initiative led by the Swiss Polar Institute (SPI), the Antarctic and Arctic Research Institute (AARI) and GEOMAR Helmholtz Centre for Ocean Research Kiel (GEOMAR) and funded by the Swiss Polar Foundation, AARI, Minobrnauki (CATS RFMEFI61619X0108) and BMBF (CATS 03F0831).

title: Physical oceanography water bottle samples based on Ocean City CTD during POLARSTERN cruise PS122

description: This data set contains the hydrographic water sample data collected with a CTD rosette in a shelter on the ice (Ocean City) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). The CTD is an SBE911plus with 12 bottles, 5 liters each, operated with a small winch and crane in the shelter on the ice. The data set contains calibrated and quality-controlled parameters (temperature, conductivity, oxygen and their derived variables) as well as only pre-cruise calibrated parameters where no post-cruise calibration or quality control was applied (all other). CDOM fluorescence data are the exception. Quality control was performed but data have to be handled with care, as the sensor seems to have broken down during leg 3 such that no post-cruise calibration could be applied. Due to issues during processing SPAR data is missing in the bottle data. The data are provided as text file (all cruise legs in one file) as well as in netCDF format (one file per cruise leg). The accuracy for salinity and conductivity is 0.004 while the accuracy for temperature is 0.002. Additional information on the sensor used for the final data set, the water depth as well as the availability of profile or bottle data is given in a separate info-text-file. Contact: Sandra.Tippenhauer@awi.deQuality flags are given based on paragraph 6. "Quality flags" from https://www.seadatanet.org/content/download/596/file/SeaDataNet_QC_procedures_V2_%28May_2010%29.pdf. QC flag meanings: 0 = unknown, 1 = good_data, 2 = probably good_data, 3 = probably bad data, 4 = bad data set to nan.This work was carried out and data was produced as part of the international Multidisciplinary drifting Observatory for the Study of the Arctic Climate (MOSAiC) with the tag MOSAiC20192020. We thank all persons involved in the expedition of the Research Vessel Polarstern during MOSAiC in 2019-2020 (AWI_PS122_00) as listed in Nixdorf et al. (2021).

title: Physical oceanography during POSEIDON cruise POS470 in Madeira basin in May/June 2014

description: During the cruise POS470 on board the German R/V Poseidon, we measured temperature, salinity, dissolved oxygen, fluorescence and turbidity on 33 stations in the Madeira Basin, Northeast Atlantic in May and June 2014. We aimed to study the physical and biogeochemical conditions in the upper 2000 m of the water column in the catchment area of Kiel 276. The CTD stations are distributed along three meridians (23°W, 22°W, and 21°W) and between 30° and 37°N to locate the Azores Front. The dissolved oxygen data is noisy below 1700 m. Since there was no measurement of dissolved oxygen (Winkler titration) during the cruise, the data cannot be calibrated.
