Ulf Erlingsson, Ph.D.

Ulf Erlingsson, PhD


Highlights

  • Invented the SediMeter, manufactured by Lindorm, Inc.
  • Proposed the Captured Ice Shelf hypothesis, which provides a mechanism for ice age jökulhlaups, and suggested an explanation for the sudden end of the ice age.
  • Equipped and used the Akusta marine geological research vessel, a trailer boat with side-scan sonar, sub-bottom profiler, echo-sounder, and precision positioning system.
  • Designed a water wave reflector that does not restrict currents.
  • Created HazMit, a natural hazard mitigation GIS system for the government of Nicaragua.
  • Written Atlantis from a Geographer's Perspective, examining Plato's tale and our folly.

  • Education: PhD in Physical Geography 1990, Uppsala University, Sweden. BSc in Earth Sciences 1984, Lund University, Sweden. Post-doctoral fellowship at Copenhagen University, Denmark.

    Areas of interest: Geomorphology, sediments, under water studies. Sediment erosion, transport, deposition, and siltation in reservoirs, lakes, coast and sea. Floating peat islands. Natural hazards, theory and palaeoevents. Quaternary geology, glaciology, palaeoclimate, palaeogeography, dynamics of ice ages, megafloods, and geomythology.

Principal research engineer, researcher, and research assistant in Uppsala University during 1988-91 and 1994-95. Scholarship in Copenhagen University during 1992-93.

    Academic: Teaching oceanography, geology, and environment, at Barry University.

    Key techniques and methods: Data collection, side scan sonar, sediment echo sounding, depth surveying, computer mapping, GIS, computer modelling, electronic measurement, multimedia, and digital publishing.

    Key projects: Floating islands in the Arenal Reservoir, Costa Rica. Supervisor on the spill monitoring programme from dredgings for the Öresund Link. Effects of flushing in the Cachí Reservoir, Costa Rica. Denudation of the Surtsey group volcanoes, off Iceland (research project). Baltic University GIS Project, BUGIS. Ooid field studies, the Bahamas and Egypt (research project). Webmaster for the University GIS Network from Oct 1994 to 1996, and for AB Hydroconsult from Aug 1995 until 2006. Designed and produced a GIS Tutor on CD-ROM in 1994-95. Planned, equipped and operated "Akusta", a marine geologic research vessel at Uppsala University. Created MESTSEM, a computer model for sediment sorting under the combined influence of waves and currents.

    Awards: Linnaeus prize 1991 from Royal Society of Sciences, Uppsala.

    Honor positions: Scientific board of the GIS Planet 2005 conference in Portugal. Chairman and other board positions in the Geographic Society of Uppsala.

    Languages: Swedish, English, Spanish, French.

    Hobbies: Diving, sailing, flying, paragliding.
