A comprehensive study of the Earth System and its different environments requires understanding multi-dimensional data acquired with a multitude sensors or produced by various models. Here we present component-wise scalable web-based framework for simultaneous visualisation multiple sources. It helps contextualise mixed observation simulation in time space. This work is an extended version conference paper (Buck et al., 2021).
Modern technology like cell phones, wind power plants or electric cars require resources such as certain metals rare earth elements with limited deposits on land, expensive difficult to obtain. Consequently, in the oceans polymetallic nodules, massive sulfides and cobalt crusts are becoming more interesting for mining companies. Since deep sea needs careful consideration mapping of concerned locations, might ecological compensation areas, is a huge endeavor enormous costs, logistics...
Autonomous underwater vehicles (AUVs) equipped with multibeam echosounders (MBES) are essential for collecting high-resolution bathymetric data in the deep sea. Navigation of AUVs and accuracy acquired MBES is challenging, especially water or rough terrain. Here, we present AUV Abyss operational workflow that uses mission planning together a long baseline (LBL) positioning network, systematic post-processing using feature matching. The enables autonomous exploration even difficult terrain,...
Ocean science and hydroacoustic seafloor mapping rely on accurate navigation underwater. By exploiting terrain information provided by a multibeam echosounder system, it is possible to significantly improve map quality. This article presents an algorithm capable of improving quality accuracy aligning consecutive pings tiles that are matched pairwise. A globally consistent solution calculated from these matches. The proposed method has the potential be used online in addition other solutions,...
The AUV Abyss post-processing workflow is published as Jupyter Notebooks complementing the IEEE OES 2018 conference contribution AUV workflow: autonomous deep sea exploration for ocean research (Klischies et al., 2018). publication explains application and use of these Notebooks in detail. The purpose of Juypter to share, adapt, execute document post- processing MBES data.
This paper presents an artificial intelligence (AI) for the board game 'Quarto!' in Java. The program uses depth-first search decision making. To improve runtime performance, we used alphabeta pruning, a transposition table, and Java constraint solver. result of our work is open-source capable beating human opponents real-time.
Where fine-grained marine sediments are being brought in suspension and become subject to transport by currents, aggregation of cohesive primary particles (flocculation) can occur. By changing the inherent particle properties, flocculation processes play an important role speeding up settling redeposition sediment particles. However, while numerous laboratory experiments have been conducted understand properties behavior flocs, so far, there is not yet appropriate method monitor in-situ....
