Multibeam bathymetry raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS132

Multibeam data were collected with RV Polarstern along the route of cruise PS132 and data acquisition was continuously monitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVPs were retrieved from CTD data. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18). SVP data were applied during acquisition. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Teledyne/Atlas multibeam processing format (.asd) were recorded with Teledyne/Atlas Parastore software as well as Teledyne Reson format (.s7k) in Teledyne PDS. Raw data files can be processed using software packages like CARIS HIPS/SIPS. For updated vessel configuration files check further details.

Biotopkartierung (SH4) Marine Daten

Der vorliegende Geodatensatz umfasst alle bis zum angegebenen Stand kartierten bzw. abgegrenzten FFH-Lebensraumtypen (= LRT) der Meeresgewässer und Gezeitenzonen (1110, 1130. 1140, 1160, 1170) ohne die LRT 1110 und 1170 der Ostsee, für die ein separater Datensatz bereitgestellt wird. Die Abgernzungen in der Nordsee wurden durch die zuständige Nationalparkverwaltung durchgeführt bzw. mit ihr abgestimmt und spiegeln den aktuellen Kenntnisstand wieder. Die Abgrenzungen in der Ostsee wurden in Abstimmung mit der Abteilung Wasserwirtschaft, Dezernat Küstengewässer z. T. anhand von Tiefenlinien und Exposition durchgeführt. Die Abgrenzungen erfolgten i. d. R. nicht durch tatsächliche Kartierung im klassischen Sinne durch Inaugenscheinnahme, sondern durch Detektion (z.B. Sonar) und dient in erster Linie der Abgrenzung LRT zur Erfüllung europarechtlicher Berichtspflichten. Die Anspache der z.T. flächenidentischen gesetzlichen Biotope sowie die Bewertung des Erhaltungsgrades der LRT wird in diesem Datensatz nicht abgebildet. Weitergehende Erläuterung zum Begriff "Wertbiotop": Im Rahmen der BK gehören zu den Wertbiotopen grundsätzlich alle Flächen, die entweder als gesetzlich geschützte Biotope gemäß § 30 BNatSchG i. V. m. § 21 LNatSchG gelten und/oder als Lebensraumtyp (LRT) gemäß Anhang I der FFH-Richtlinie (92/43/EWG, 21.05.1992) anzusprechen sind. Hinsichtlich des gesetzlichen Biotopschutzes ist der Stand nach der Novellierung des Landesnaturschutzgesetzes (LNatSchG) in 2016 (Veröffentlichung in dem GVO Nr. 7 vom 23.06.2016, Seite 162) berücksichtigt und schließt das „arten-und strukturreiche Dauergrünland“ mit ein. Auch die Änderungen aufgrund des § 21 Absatz 7 des Landesnaturschutzgesetzes (LNatSchG), zuletzt geändert durch Verordnung vom 27. März 2019 (GVOBl. Schl.-H. S. 85), sind berücksichtigt sowie - soweit bereits erhoben bzw. in Schleswig-Holstein überhaupt v.h. - auch die seit dem 1. März 2022 gem. § 30 Absatz 1 Nummer 7 BNatSchG neu erfassten gesetzlich geschützten Biotope. Zu den Wertbiotopen gehören im vorliegenden Geodatensatz sämtliche Flächen/ Geometrien, die in den Tabellenspalten „BTSCHUTZ_1“ und/oder „BTSCHUTZ_2“ der Attributtabelle einen Eintrag einer Biotopverordnungsnummer (VO) oder die in den Tabellenspalten „LRT_TYP_1“ und/oder „LRT_TYP_2“ einen Eintrag eines Natura 2000- bzw. EU-LRT-Codes aufweisen. Nachrichtlich weist das LfU darauf hin, dass der Schutz des § 30 BNatSchG i. V. m. § 21 LNatSchG aktiviert wird, wenn und sobald eine Fläche die charakteristischen Merkmale eines gesetzlich geschützten Biotopes erfüllt. Der in § 30 Abs. 7 thematisierten Registrierung, die sich nach Landesrecht richtet und zumeist in Biotopkartierungen, Listen oder Biotopverzeichnissen ihren Niederschlag findet, kommt daher eine lediglich deklaratorische Bedeutung zu. D.h. nicht erst durch die Kartierung bzw. Erfassung und Registrierung werden Flächen zum geschützten Biotop, sondern der Charakter als gesetzlich geschütztes Biotop ergibt sich unmittelbar aus dem Gesetz. Bei Fragen und in Zweifelsfällen ist mit der fachlich zuständigen Person im LfU Rücksprache zu halten. Hinweis: Daten der maritimen LRT 1110 und 1170 in der Ostsee, befinden sich in dem separaten Geodatensatz "Maritim_Daten_Ostsee_LRT_1110_und_1170".

Multibeam bathymetry processed data (EM 1002 echosounder entire dataset) of RV MARIA S. MERIAN during cruise MSM52

Swath sonar bathymetry data used for that dataset was recorded during RV MARIA S. MERIAN cruise MSM52 using Kongsberg EM1002 multibeam echosounder. The cruise took place between 01.03.2016 and 28.03.2016 in the Baltic Sea. The cruise aimed gapless imagining of the major pre-alpine tectonic lineaments due to the fact that the Glückstadt Graben and the Avalonia-Baltica suture zone run across the southern Baltic [DOI: 10.2312/cr_msm52]. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. During the MSM52 cruise, the moonpooled KONGSBERG EM1002 multibeam echosounder (MBES) was utilized to perform bathymetric mapping in shallow depths. It has a curved transducer of which 111 beams are formed for each ping while the seafloor is detected using amplitude and phase information for each beam sounding. For further information on the system, consult https://www.km.kongsberg.com/. Generally, the system was acquiring data throughout the entire cruise. Responsible person during this cruise / PI: Laura Frahm. Postprocessing and products were conducted by the Seafloor-Imaging & Mapping group of MARUM/FB5, responsible person Paul Wintersteller (seafloor-imaging@marum.de). The open source software MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, https://www.mbari.org/products/research-software/mb-system, 2017) was utilized for this purpose. A sound velocity correction profile was applied to the MSM52 data; there were no further corrections for roll, pitch and heave applied during postprocessing. A tide correction was applied, based on the Oregon State University (OSU) tidal prediction software (OTPS) that is retrievable through MB-System. CTD measurements during the cruise were sufficient to represent the changes in the sound velocity throughout the study area. Using Mbeditviz, artefacts were cleaned manually. NetCDF (GMT) grids of the edited data as well as statistics were created with mbgrid. The published bathymetric EM1002 grid of the cruise MSM52 has a resolution of 35 m. No total propagated uncertainty (TPU) has been calculated to gather vertical or horizontal accuracy. A higher resolution is, at least partly, achievable. The grid extended with _num represents a raster dataset with the statistical number of beams/depths taken into account to create the depth of the cell. The extended _sd -grid contains the standard deviation for each cell. The DTMs projections are given in Geographic coordinate system Lat/Lon; Geodetic Datum: WGS84.
