    Description: Highlights: • Unique 30-years data of currents and temperature below 1000 m in the Madeira Basin. • Inter-decadal and long term changes were examined between 1000 m and the bottom. • Temperature increase by 0.03 ± 0.01 °C/year (1000 m) and 0.02 ± 0.02 °C/year at 1600 m. • No significant changes at 3000 m and 5000 m at long-term scale. • The currents and kinetic energy increased in the entire water column over 30-years. Abstract: Data from the deep-sea mooring Kiel 276 (33 N, 22W), 5300 m water depth in the northeast Atlantic, was used to investigate the temporal variability of temperature and currents below the main thermocline (1000 m, 1600 m, 3000 m, 5000 m) in the 30-year period (between 1980 and 2009). Daily averages were the basis to assess the temperature and currents changes, as well as kinetic energy, from annual to decadal and long-term scales. Below the main thermocline, no seasonal signal was identified for both, temperature and currents, during the 30 years. The record-length linear temperature trends at 1000 m and 1600 m are 0.03 ± 0.01 °C year−1 and 0.02 ± 0.02 °C year−1, respectively. The mean currents also intensified within the decades in the entire water column, and as a consequence, the mean kinetic energy increased. The fluctuating kinetic energy increased on a decadal scale only at 1000 m, as a possible consequence of the increase in the strength of Mediterranean Water lenses (MEDDIES) that crossed the mooring site. During the period 2001–2009, six MEDDIES crossed the Kiel 276 site, in addition to the 10 MEDDIES identified earlier during the previous 20 years, between 1980 and 2000 (Siedler et al., 2005). The integral time scales are of the same order in all depths (between 30 to 40 days), indicating that events occur on similar time scales, with mesoscale signals dominating and being present within the entire water column.

    Hydrochemistry measured on water bottle samples during the cruise Hai Yang Di Zhi Shi Hao in South China Sea in September 2018 (2021)

    Details
    Publication Date: 2024-05-08
    Description: During the cruise H10-2018 on board the Chinese R/V Hai Yang Di Zhi Shi Hao, we collected water with a CTD SBE911 rosette system in 64 stations distributed along the shelf, shelf edge and deep-sea of the northern South China Sea. We aimed to study the nutrients availability and primary production distribution under the influence of the strong typhoon Mangkhut, in September 2018. The influence of the Mangkhut typhoon over the upper 100 m of the water column was accessed before and after its passage. The physical oceanography during the survey is available at PANGAEA (Waniek et al., 2021). Brief description of the methodology used: - Nitrate, nitrite, phosphate and silicate were measured by continuous flow analysis. - Oxygen was measured on one sample at each station by potentiometric Winkler titration. - DOC and DN were measured by catalytic oxidation after filtered with GF/F-filters. - POC and PON were measured by means of an elemental analyser after filtered with pre-combusted GF/F-filters. - Suspended particulate material (SPM) was determined gravimetrically after pre-combusted and weighted GF/F-filters filtration. - Chlorophyll a and phaeopigments were measured using a fluorometer after ethanol extraction of the GF/F-filters. More information regarding the methodology used can be seen in Kuss et al. (in review).

    Physical oceanography during POSEIDON cruise POS470 in Madeira basin in May/June 2014 (2022)
    PANGAEA
    Details
    Publication Date: 2024-05-08
    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.
