title: Chemical concentration of major metal and rare reath elments (REE) in sediments assocaited with manganese nodules

description: Sediment samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and minor element geochemistry of the deposits by Clavert and Price, 1977 (see Related to: reference). The powdered samples were leached with 0.1 M HCl at a ratio of 1:4 by weight at room temperature for 140 days after which the leachate and the residue were separately analyzed. The determinations of Fe, Mn, (atomic absorption spectrophotometry) and P (calorimetry) were made on the leachate. The REE were analysed by mixed-solvent ion exchange and mass spectrometric isotope dilution. Isotope analyses were performed on an A.E.I. MS5 mass spectrometer. RMS precision were generally 2% (and often 1%). except for La (5%). Eight replicate analyses of USGS standard rock BCR-1 were used for comparison.
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.This dataset represents the digitized Table2 - Part 2, pp. 516 of the related publication.

title: Positioning and telemetry from ROV survey PS122/1_10-113 on 2019-12-06, survey 1

description: The horizontal position of the remotely operated vehicle (ROV) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition between November 2019 and September 2020 was measured using an acoustic Long Base Line (LBL) positioning system (LinkQuest Pinpoint). The position was recorded in the SPOT.ON survey systems software (OceanModulesTM). The track was smoothed from initial acoustic fixes and cleaned for most obvious outliers. The position is in a floe-fixed, relative coordinate system (X, Y) with the origin (X=0 m, Y=0 m) at the ROV hole. A quality flag for the position is introduced based on the time to the closest fix with “1” indicating good positon (fix reached &lt;= 3s), “2” medium position (fix reached &gt; 3s & &lt;= 5s), and “3” bad position (fix reached &gt; 5s). Depending on the scientific aim, a position with quality flag “3” can still be useful. Vehicle depth was measured by the integrated pressure sensor and calibrated to 0 during pre-survey procedures, when the top side of the vehicle was at the same level as the water surface. Vehicle attitude (roll, pitch, heading) was measured with an onboard inertial measuring unit (IMU, Microstrain) with three axis accelerometer, magnetometer and gyroscope. Depth was measured by a pressure sensor (Keller A-21Y, Keller AG) included in the main electronics housing of the ROV.
