"Operative Ontologien werden in diesem Artikel als relationale kommunikative Situationen vorgestellt, in denen Medien und Technik Teil einer Praxis sind, aber nicht einfach mit dieser zusammenfallen. Die Ontologie bezieht sich auf eine temporäre Konstellation, beispielsweise eine Verknüpfung von Maschine, Körper und Bild, in der die ontologische Frage der Anthropologie perspektivisch immer wieder verschoben wird. Wie das genau zu verstehen ist, wird am Fallbeispiel der Motion-Capture-Technik deutlich, in der durch eine Verschmelzung von Live Action Movie und der animierten Welt der Visual Effects eine permanente Veränderung dessen erfolgt, was als Mensch oder menschliche Umwelt angesehen wird. This article presents operational ontologies as communicative situations in which media and technology are part of a practice, but do not simply coincide with it. Ontology refers to a temporary constellation, for example a link between machine, body and image, which shifts the ontological question of anthropology in perspective time and again. This thesis is further illustrated by a case study of the motion capture technique, whose merging of live action movie and the animated world of visual effects leads to a permanent modification of our notions of the human being and human environment.

Research on human-environment interactions often neglects the resources of the humanities. Hurricane Katrina and the resulting levee breaches in New Orleans offer a case study on the need for inclusion of the humanities in the study of human-environment interactions, particularly the resources they provide in examining ethics and value concerns. Methods from the humanities, when developed in partnership with those from the sciences and social sciences, can provide a more accurate, effective, and just response to the scientific and technological challenges we face as a global community.

In this paper, we advocate a collaborative approach to investigating past human–environment interactions in southwest Madagascar. We do so by critically reflecting as a team on the development of the Morombe Archaeological Project, initiated in 2011 as a collaboration between an American archaeologist and the Vezo communities of the Velondriake Marine Protected Area. Our objectives are to assess our trajectory in building collaborative partnerships with diverse local, indigenous, and descendent communities and to provide concrete suggestions for the development of new collaborative projects in environmental archaeology. Through our Madagascar case study, we argue that contemporary environmental and economic challenges create an urgency to articulate and practice an inclusive environmental archaeology, and we propose that environmental archaeologists must make particular efforts to include local, indigenous, and descendent communities. Finally, we assert that full collaboration involves equal power sharing and mutual knowledge exchange and suggest an approach for critical self-evaluation of collaborative projects.

Satellite remote sensing is a valuable tool for coastal management, enabling the possibility to repeatedly observe nearshore sandbars. However, a lack of methodological approaches for sandbar detection prevents the wider use of satellite data in sandbar studies. In this paper, a novel fully automated approach to extract nearshore sandbars in high–medium-resolution satellite imagery using a GIS-based algorithm is proposed. The method is composed of a multi-step workflow providing a wide range of data with morphological nearshore characteristics, which include nearshore local relief, extracted sandbars, their crests and shoreline. The proposed processing chain involves a combination of spectral indices, ISODATA unsupervised classification, multi-scale Relative Bathymetric Position Index (RBPI), criteria-based selection operations, spatial statistics and filtering. The algorithm has been tested with 145 dates of PlanetScope and RapidEye imagery using a case study of the complex multiple sandbar system on the Curonian Spit coast, Baltic Sea. The comparison of results against 4 years of in situ bathymetric surveys shows a strong agreement between measured and derived sandbar crest positions (R2 = 0.999 and 0.997) with an average RMSE of 5.8 and 7 m for PlanetScope and RapidEye sensors, respectively. The accuracy of the proposed approach implies its feasibility to study inter-annual and seasonal sandbar behaviour and short-term changes related to high-impact events. Algorithm-provided outputs enable the possibility to evaluate a range of sandbar characteristics such as distance from shoreline, length, width, count or shape at a relevant spatiotemporal scale. The design of the method determines its compatibility with most sandbar morphologies and suitability to other sandy nearshores. Tests of the described technique with Sentinel-2 MSI and Landsat-8 OLI data show that it can be applied to publicly available medium resolution satellite imagery of other sensors.
