Historical digital terrain model data of the Weser Estuary (HIWEST)

The Weser estuary at the German North Sea coast serves as a fairway to the harbours of Bremerhaven and Bremen. To ensure safe shipping and navigation, the navigation channel depths are nowadays intensively monitored, and have been so in the past. These are valuable data for consulting and research purposes, and enables investigations leading to a better understanding of hydrodynamics, salt intrusion and morphological processes in the estuary, in the present as well as the past. For recent years, thanks to modern monitoring techniques and digitalization, measuring data has been compiled to consistent digital terrain models of high quality and accuracy. For time periods before the 1990ies however, measurements were scarcer and the data are available only in form of printed bathymetrical and nautical charts. The objective of the project “Historical system states of the Weser estuary (HIWEST)” was to: • digitalize depths measurements starting from 1960, • georeference the data points and • process and compile them to digital terrain models that can be used for research and consulting. The project was led and financed by the Federal Waterways Engineering and Research Institute (BAW). It was supported by the Federal Maritime and Hydrographic Agency (BSH) and by the German Water and Shipping Administration (WSV) who provided printed charts and scanned data sets. The smile consulting GmbH was contracted to process the data and compile digital terrain models. One of the main challenges of the project was georeferencing. While georeferencing and projecting in the horizontal domain was comparatively straightforward, the transformation of depths below different chart datums to the Germans mean height reference system represented a challenge. This was accomplished by an algorithm considering spatial polygons provided by BSH and further meta information on the different levelling systems. The accuracy of the data sets differs depending on the quality of the original data. Since the 1990ies, powerful measurement methods such as airborne laser scanning (ALS) and multibeam echo-sounding has led to high resolutions and high data accuracy. In past surveys, the depths were measured in single-beam echo-soundings, often along individual cross sections, and there is no information between these soundings. As a result, the older terrain models are much smoother then the newer ones and contain less detailed information. More technical details can be found in the appendix of the technical report. The following digital terrain models (DTM, in the following the German abbreviation DGM is used) of the Lower and Outer Weser estuary were made available: • DGM 1966, marking the situation before deepening the Outer Weser to SKN-12 m</li> • DGM 1972, marking the situation before deepening the Lower Weser to SKN-9 m</li> • DGM 1981, marking the situation before extensive river works in the Lower Weser</li> • DGM 1996, marking the situation before deepening the Outer Weser to SKN-14 m</li> • DGM 2002, marking the situation after deepening the Outer Weser to SKN-14 m, reference digital terrain model. The years were chosen so they would represent consistent periods not affected by constructive engineering measures such as channel deepenings, and secondly based on optimal data availability. Each data set however consists not only of data from the respective year, but data had to be added from adjacent years. To close gaps, data from recent surveys were used. The data sets span the whole estuary from the North Sea to the tidal weir in the city of Bremen and are available as 1x1 m raster data sets.

Arctic PASSION - Polar Monthly Mean Ice Surface Temperature (AP-MMIST) for the time period 1982 to 2024

The Arctic PASSION Polar Monthly Mean IST data set (AP-MMIST) is a combined surface temperature product covering open ocean, marginal ice zone and closed sea ice areas, represented by Sea Surface Temperatures (SST), Marginal Ice Zone Temperatures (MIZT) and sea Ice Surface Temperatures (IST). Beside ocean and sea ice the data set also includes surface temperatures from the Greenland and Antarctic ice sheets. AP-MMIST has been jointly developed and produced by Arctic PASSION WP-1 and the Sea Ice Thematic Assembly Centre (Sea Ice TAC) under the Copernicus Climate Change Service (C3S - service contract: 2022/C3S2_312b_MOi_SC1). The AP-MMIST is a monthly averaged temperature product based on the C3S daily IST CDR and ICDR level 3 data. The daily mean C3S IST data set is a resampled and averaged daily mean IST product using Global Area Coverage - Advanced Very High-Resolution Radiometer (AVHRR) IST level 2 data as input. The level 2 and 3 CDR and ICDR data records are described in Algorithm Theoretical Baseline Document (Eastwood et al., 2023). The surface temperature retrieval algorithm used to produce the basic level 2 product is a traditional split window algorithm using two Thermal InfraRed (TIR) channels to compensate for atmosphere and angular emissivity dependency. This is described in the Algorithm Theoretical Baseline Document (Eastwood et al., 2023). The level 1 TIR input data set is the full data record from the AVHRR on-board NOAA satellite platforms since 1982, as well as AVHRR records on-board Metop satellites since 2006. The product output format is NetCDF with standard attributes, following CF convention to the degree possible. The monthly data are divided into 2 monthly files, one for each hemisphere, SH and NH.

Schwerpunktprogramm (SPP) 2451: Lebende Materialien mit adaptiven Funktionen, Teilprojekt: Konstruktion lebender Aktoren aus fädigen Cyanobakterien

In diesem Projekt schlagen wir eine experimentelle und theoretische Zusammenarbeit vor, um lebende Aktuatoren aus gleitenden, fädigen Cyanobakterien zu entwickeln. Diese phototrophen Organismen spielen sowohl aktuell als auch historisch eine wichtige Rolle im Kohlenstoffkreislauf der Erde, da sie beispielsweise den atmosphärischen Sauerstoff und große Teile unserer fossilen Brennstoffe erzeugten. Filamente bestehen aus vielen linear verketteten Zellen. Sie haben einen Durchmesser von nur wenigen Mikrometern, können aber bis zu einigen Millimetern lang werden. In Kontakt mit festen Oberflächen oder anderen Fäden gleiten sie entlang ihrer Kontur und reagieren auf Lichtgradienten durch Richtungsumkehr. Die zu Grunde liegenden Mechanismen sind noch nicht vollständig geklärt. In natürlichen Lebensräumen führt diese Bewegung zur Aggregation in dichte Kolonien, die sich je nach Umgebungsbedingungen zusammenziehen oder wieder zerstreuen können, was eine kollektive Akklimatisierung ermöglicht. Wir werden diese Eigenschaften nutzen, um anpassungsfähige lebende Aktuatoren zu entwickeln, d. h. ein Material, das durch Stimulation mit Licht seine Form verändern kann. Die Bakterien werden in eine Matrix eingebettet, typischerweise ein gel- oder faserbasiertes Material mit maßgeschneiderten Eigenschaften und Strukturen, die im Projekt entwickelt werden. Indem wir die Bakterien mit Hilfe von Lichtmustern steuern und ausrichten, wollen wir ein aktives Netzwerk im Gerüst aufbauen, das sich bei Stimulation zusammenziehen kann. Die Kräfte aus dem aktiven Netzwerk werden entweder durch Adhäsion oder mechanische Verzahnung zwischen aktiven und passiven Komponenten übertragen. Durch die Abstimmung der gegenseitigen Ausrichtung von aktiven und passiven Netzen und ihrer Anisotropie wollen wir eine Kontrolle der Deformation erreichen. Auf langen Zeitskalen wird das Material adaptiv sein, da langfristige einwirkende Lichtmuster eine topologische Neuordnung des aktiven Netzes bewirken, so dass zwischen verschiedenen Aktuationsmodi gewechselt werden kann. Die Entwicklung von Manipulationsstrategien, die in der Lage sind, mechanische Arbeit zu extrahieren, erfordert Kenntniss der raum-zeitlichen Organisation der Krafterzeugung einzelner Filamente und ihrer Ensembles, welche bisher nicht verfügbar ist und in diesem Projekt gewonnen werden soll. Im Gegensatz zu den meisten bisher untersuchten lebenden Aktuatoren basiert unser System auf langen, flexiblen und beweglichen polymeren Bestandteilen, die äußerst robust und von Natur aus durch Licht stimulierbar sind: Die Fasernatur der lebenden Bestandteile ermöglicht es, stark verflochtene Netzwerke zu schaffen, die in einem breiten Spektrum von Umgebungsbedingungen bestehen können. Ihre Beweglichkeit und Reaktionsfähigkeit ermöglicht es, das Netzwerk selbst zu aktivieren, ohne dass die lebenden Bestandteile aufwendig modifiziert werden müssen.
