The Offices and the Ocean Earth Construction and Development Corporation firm has come to be a vehicle for gathering authoritative evidence, such as detailed maps and satellite images, for what is described in the 1989 scientific conference
Global Monitoring and Assessments: Towards the 21st Century as "ocean-basin monitoring and management." Precise maps mosaiced from aeronautical charts have been produced to include what UNEP documents call "land-based sources of pollution", or all possible terrain for drainage, for each regional sea. This would include, as shown in
Documenta in 1992, the Black Sea, Baltic Sea, North Sea, and both the entire Mediterranean Sea and subsets thereof, like the Adriatic. The practice of basin mapping has been continued with bays, relying on an Irish law from 1959 defining "
hydrometric areas" as any
drainage basin for a bay including all bay waters extending out six miles beyond the outermost points of the bay. Such detailed hydrometric-area mapping has been conducted for the British Isles, New Zealand, Italy, parts of the Eastern Europe and both North and South America.
Plans for the Adriatic Basin were presented in the Venice Biennale Aperto of 1993, under the label "Oil-Free Corridor." These were pursued further with "On Board", in the 1995 Biennial, curated by
Jerome Sans with action in the Venice Lagoon. Specifics were presented in the Architecture Biennail of 2008. In 2000, he was part of the three person show
Ecologies at the
Smart Museum of Art in
Chicago with
Mark Dion and
Dan Peterman. Each artist "explored interrelationships between organisms and their surrounding" and Fend's featured work was titled
China Basin Plans: The River Dragon Breathes Fire. ==Bibliography (selection)==
