title: Hydrographic observations from Hornsund fjord, Svalbard, 2015-2023

description: Annual hydrographic monitoring of Hornsund fjord in southern Svalbard began in 2015. The observations span over several months, typically from May to October, each year. Vertical CTD (conductivity-temperature-depth) -profiles obtained regularly from 11 stations across the Hornsund fjord form the core of the hydrographic observations. The data has been collected using Valeport miniCTD and SAIV A/S SD208 CTD, of which the latter has been accompanied with oxygen and turbidity sensors. Thermodynamic variables (potential temperature, salinity, density and sound velocity) are derived from the raw data. The data has been filtered and the vertical profiles averaged to 1-dbar bins. The data has passed a careful visual quality control. Further details on the data collection and processing can be found in the manuscript mentioned below. The monitoring is still ongoing and the datasets will be updated annually at the data portal of Institute of Geophysics Polish Academy of Sciences (https://dataportal.igf.edu.pl/group/longhorn). The raw CTD-data is also available at the same data portal.

title: Ocean bottom seismic data from the continent-ocean transition in the Deep Galicia Margin, offshore west Iberia: active source data

description: Seismic data was acquired to study the transition from rifted continental crust to oceanic crust at the Deep Galicia Margin from June to August 2013. 3D Multichannel reflection and coincident wide-angle seismic data were acquired simultaneously as part of a seismic experiment over an area of 80 km long and 25 km wide in the Deep Galicia margin. The multichannel reflection seismic volume was acquired by the R/V Marcus G. Langseth, which provided a source for the ocean bottom seismic data. A total of 86 ocean bottom hydrophones/seismometer deployments were carried out by F/S Poseidon. Two airgun arrays with total gun volumes of 3,300 cu.in. were deployed as seismic sources. Shots were fired alternately using two source arrays every 37.5 m (shot interval of ~ 16 s with ship speed of 4.5 knots). Data were converted into SEGY format. Further details are available at https://doi.org/10.1038/NGEO2671.

title: Underway measurements of dissolved oxygen, total dissolved gas pressure, fluorescence and turbidity during RV METEOR cruise M160

description: Underway data for dissolved oxygen, total dissolved gas pressure, fluorescence and turbidity have been collected along the track of the RV METEOR cruise M160 around the Cape Verde archipelago. Water was pumped from the moon pool at 5 m depth into an insulated box, where the sensors were located. Discrete samples for dissolved oxygen were taken from the water stream and analysed on board by Winkler titration to correct the sensor data. Salinity data used for corrections and conversions was taken from the shipside TSG measurements at 5m depth.
description: Continuos sensor data for dissolved oxygen, total dissolved gas pressure, fluorescence and turbidity. While the dissolved oxygen data was corrected using discrete winkler titration samples taken from the same water stream, fluorescence an turbidity values are given in arbitrary units, as the sensor was not calibrated. No specific data correction was applied to the total dissolved gas pressure values, as the sensor is not known to drift.

title: Limnological properties of thermokarst lakes in Central Yakutia sampled between 2018-2019

description: This dataset compiles selected limnological properties of a series of thermokarst (thaw) lakes in Central Yakutia (Eastern Siberia). These properties were measured during fall 2018 (September), winter 2019 (March-April), spring 2019 (May), and summer 2019 (August). These data span four seasons (Fall, Winter, Spring, and Summer) 2018-2019. The lake type designation is based on field observations, past radiocarbon dating of lake sediments, geochemical signatures of lake waters, and a multiple-stage development model of thermokarst lakes. Data were collected at the surface (~ 30 cm depth) from lake shores. Specific conductivity (accuracy ±1% of reading), temperature (accuracy ±0.2°C), dissolved oxygen (accuracy ±1% of reading or 1% saturation) and pH (accuracy ±0.2) were measured using a YSI Pro DSS multiprobe sensor. Water samples were collected to analyze dissolved organic carbon (DOC). Samples were filtered using baked glass fiber filters (Whatman GF/F, 0. 7µm), acidified to pH 2 with ultra-pure HCl and stored in baked glass vials. DOC concentration was measured using a TOC-5000A analyzer (Shimadzu, Japan). The quantification limit was 1 mg L-1. Above this value, the analytical uncertainty was estimated at ±0.1 mg L-1. Reference material included ION-915 ([DOC]= 1.37 ± 0.41mg C L-1) and ION 96.4 ([DOC]= 4.64 ± 0.70 mg C L-1) (Environment and Climate Change Canada, Canada).

title: Ocean data of the Drift Towing Ocean Profiler (DTOP) from buoy 2018, deployed during Chinese Arctic Research Expedition 2018

description: Vertical profiles of water temperature, salinity, dissolved oxygen and chlorophyll were measured by the Drift Towing Ocean Profiler (DTOP) buoy 2018, an autonomous platform, installed on drifting sea ice (ice thickness: 155cm; snow depth: 5cm; freeboard: 10cm) in the Arctic Ocean during Chinese Arctic Research Expedition 2018. The resulting time series describes the vertical profile of the ocean below the sea ice as a function of place and time between 22 August 2018 and 24 December 2018 in sample intervals of 12 hours. In addition, the DTOP measured air temperature, relative humidity and barometric pressure and GPS position at hourly intervals.
description: The data set has been processed and contains quality flags for different kinds for erroneous data. Flag values are the sum of individual error codes. The value of 0 refers to no error.Quality flag, position: The geographic position is flagged +1 if the drift velocity, as derived from the GPS longitude and latitude, exceeds a threshold of 10 deg latitude or 50 deg longitude per time step; +2 if the position exceeds extreme values, such as longitude &gt; 360 deg; +4 if the position is exactly 0.0.

title: Nutrient Data from CTD Nisken Bottles from Sonne Expedition SO-245 "UltraPac"

description: Nutrient data from Nisken Bottle samples collected and measured onboard Sonne Expedition SO-245 "UltraPac". Concentrations of dissolved inorganic phosphate (PO43-), nitrite (NO2-), nitrate (NO3-), and silicate (Si) were measured with the QuAAtro39 autoanalyser (Seal Analytical) using the method based on Strickland and Parsons, 1972. OSIL Seawater Low-Nutrient Standards were used as a secondary standard to test primary standard calibrations. Low concentrations of dissolved phosphate (&lt;300 nM) were determined with a long waveguide capillary cell (LWCC) set-up, which included a Traacs 800 pump and autosampler, a World-Precision 100 cm LWCC, an HL 2000 Lamp from Ocean Optics and a STS-VIS Miniatur Spectrophotometer from Ocean Optics. Minimum quantifiable limits were set at 2 times the Minimum Detection Limit given for the method. Oxygen was measured on selected samples by Winkler titration for the purpose of calibrating the CTD O2 sensor. Temperature, Salinity, Sigma-Theta, and Dissolved Oxygen data are included for information and derive originally from: Zielinski, Oliver; Henkel, Rohan; Voß, Daniela; Ferdelman, Timothy G (2018): Physical oceanography during SONNE cruise SO245 (UltraPac).PANGAEA, https://doi.org/10.1594/PANGAEA.890394

title: Chemical oceanography during POLARSTERN cruise ARK-IX/4

description: Marine chemistry data (dissolved oxygen and dissolved inorganic nutrients) were collected from 10 august 1993 to 24 September 1993, during ARK IX/4cruise, along six sections stretching from the continental shelves of the Barents and Laptev Seas, over the shelf break and into the deep Eastern Nansen and Amundsen Basins. These investigations are a direct continuation of "SEAS" project in the Barents Sea (ARKVIII/2, 1991). The dataset includes discrete samples, at different depths, of 63 stations.Sampling of chemical measurements was carried out in parallel to physical-oceanography sampling and phytoplankton work using Rosette-water sampler mounted on a CTD (Neil Brown, Mark III). Discrete water samples for dissolved oxygen (DO) and dissolved inorganic nutrients (nitrate, nitrite, phosphate and silicate) were collected and analyzed directly on board of R/V Polarstern within a few hours after sampling. Dissolved inorganic nutrients (NO3+NO2, SiO4, PO4) have been measured by means of a Chemlab Continuous FloW Analyser according to the standard methods reported by Grassof 1983. Dissolved oxygen was analyzed by the Winkler method, according to Grasshoff 1983, as well.

title: Coccolithophores abundance at IODP Hole 385-U1549A in Guaymas Basin, Gulf of California

description: The sedimentary samples studied came from cores of Hole 385-U1549A (27° 28.33167' N, 111° 28.7844' W) obtained during the International Ocean Discovery Program (IODP) Expedition 385 "Guaymas Basin and Tectonics" during September-November 2019 aboard the drilling platform "JOIDES Resolution". For this work, we studied samples from the first 40 m of Hole 385-U1549A.The Hole 385-U1549A coccolith assemblage is mainly represented by 18 taxa of which the members of Gephyrocapsa group with size &gt;3 µm (Gephyrocapsa oceanica and Gephyrocapsa muellerae) is the dominant taxa of the assemblage with a relative abundance above 50 %. The members of the group of Gephyrocapsa with size &lt;3 µm (Gephyrocapsa ericsonii and Gephyrocapsa aperta) shows values around 30 %. Emiliania huxleyi and Florisphaera profunda show values around 3 %. The relative abundances of the other taxa are significantly lower including Coccolithus pelagicus, Helicosphaera carteri, Syracosphaera spp., Calcidiscus leptoporus, Umbilicosphaera spp.

title: Photos of threespine stickleback Gasterosteus aculeatus from the subarctic White Sea and table datasets in CIELAB values used for studying coloration

description: This dataset includes photographs of threespine stickleback (Gasterosteus aculeatus L.) collected in 2021 and 2023, along with raw data tables containing CIELAB color space (L*, a*, b*) values, to study pre-spawning coloration.In 2021, we made photos of sticklebacks from an experimental pool. Initially, approximately 1,100 threespine stickleback were collected from the Seldianaia Inlet on June 5, 2021, using a 7 m x 1.5 m beach seine. Spawning coloration was not observed at the time of capture. Then, fish were held in an experimental pool at the Educational and Research Station Belomorskaya of St. Petersburg State University, in Kandalaksha Bay, White Sea. The pool lacked substrate, and the water temperature was maintained at approximately 12°C under natural photoperiod conditions. Fish were held for several days to minimize stress. No breeding behavior was recorded during this experiment. Eleven days after capture, 34 females and 17 males were randomly selected for analysis. Sex was determined by observing inner mouth color (males: bright orange lips; females: pale lips) and confirmed by dissection. These fish were photographed. Individuals were photographed alive in a custom-designed wooden photo box. The camera (Canon EOS 650D) was positioned perpendicular to the shooting plane, with the lens 17 cm from the surface. Five fish were photographed at a time. Images were captured in .RAW format (3456 x 5184 pixels).In 2023 we photograhed wild fish from the Seldianaia Inlet. Thirty males and thirty females were collected from the Seldianaia Inlet on June 4, 2023, four days after their presence was noted near the university's educational and research station. Fish were collected by the same beach seine before active spawning and did not show clear signs of spawning coloration. Individuals were photographed alive in the same custom-designed wooden photo box as in 2021. The camera (RICOH WG-6) was positioned perpendicular to the shooting plane, with the lens 17 cm from the surface. Ten fish were photographed at a time. Images were captured in .JPEG format (5184 x 3888 pixels).Color correction was performed using a Datacolor SpyderCheckr24 color card, followed by processing in Adobe Lightroom and SpyderCheckr 1.3 software. All corrected images were saved in .JPEG format.ImageJ software was used to analyze the corrected images and extract the L*, a*, and b* values. Color was measured at eight standard sites (regions of interest) on each fish, covering different body parts. L*, a*, and b* values were recorded for each location. Thus, we have the raw data for 51 fish caught in 2021 from the experimental pool and for 60 fish caught in the field conditions in 2023 with the associated metadata for each subset.

title: Seawater carbonate chemistry and calcification mechanisms of three Hawaiian coral species (Montipora capitata, Porites compressa, Porites lobata)

description: Here, we used boron-based geochemical proxies (δ11B, B/Ca) to investigate how three common Hawaiian coral species (Montipora capitata, Porites compressa, Porites lobata) regulate the carbonate chemistry of the calcifying fluid along a natural environmental mosaic of seawater carbonate chemistry and significant wave height. This dataset is included in the OA-ICC data compilation maintained in the framework of the IAEA Ocean Acidification International Coordination Centre (see https://oa-icc.ipsl.fr). Original data were extracted from tables in the related paper (see Related to) by the OA-ICC data curator. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2024) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2025-08-18.
