[A very comprehensive hydrographic and shallow geophysical study and mapping effort of Lake Titicaca…]
“In October 2024, officers from the Category “A” Specialization Programme in Hydrography for Naval Officers of the Peruvian Navy conducted their complex multidisciplinary field project at Lake Titicaca at Puno in Peru, which is the highest navigable lake in the world (3,800 metres above sea level). The purpose of this survey was to address issues in the lacustrine environment due to hydrological processes that have occurred in recent years in this water body.…”

Last fall, Mike Tilston and I joined #HakaiInstitute to survey the upper part of the fjord with a #multibeam sonar to study the #geomorphic impacts of the turbidity current. We were joined by #GeologicalSurveyofCanada
and #CoastGuard, who surveyed the rest in their much bigger ship the #Vector.
