Stamukhi lakes are vast but little-explored Arctic ecosystems. They occur throughout winter, spring, and early summer near large river inflows along the Arctic coastline, and are the result of freshwater retention behind the thick barrier of rubble ice (stamukhi) that forms at the outer limit of land-fast sea ice. We examined the molecular biodiversity(More)
This article presents a novel autonomous surface vessel (ASV) that was designed and manufactured specifically for the monitoring of water resources, resources that are not only constantly drained but also face the growing threat of mass proliferation (bloom) of noxious cyanobacteria. On one hand, the distribution of these blooms in a given water body(More)
Robotic sensors are promising instruments for monitoring spatial phenomena. Oftentimes, rather than aiming to achieve low prediction error everywhere, one is interested in determining whether the phenomenon exhibits certain critical behavior. In this paper, we consider the problem of focusing autonomous sampling to determine whether and where the sensed(More)
The presence of neurotoxic species within the genus Alexandrium along the U.S. coastline has raised concern of potential poisoning through the consumption of contaminated seafood. Paralytic shellfish toxins (PSTs) detected in shellfish provide evidence that these harmful events have increased in frequency and severity along the California coast during the(More)

Seawater desalination by reverse osmosis (RO) is a reliable method for augmenting drinking water supplies. In recent years, the number and size of these water projects have increased dramatically. As freshwater resources become limited due to global climate change, rising demand, and exhausted local water supplies, seawater desalination will play an(More)
More than 70% of our earth is covered by water, yet we have explored less than 5% of the aquatic environment. Aquatic robots, such as autonomous underwater vehicles (AUVs), and their supporting infrastructure play a major role in the collection of oceanographic data. To make new discoveries and improve our overall understanding of the ocean, scientists must(More)
—With the recent increase of toxic algal blooms in lakes, biologists are looking for new sampling methods to analyze their spatiotemporal dynamics. In this paper, we present an Autonomous Surface Vessel (ASV) capable of achieving long-term sampling missions covering up to now a transect plane (1.5 km wide and 20 m deep). The ASV is equipped with a probe(More)
The progress of science towards interdisciplinary exchange and integration of information, such as in the ArcticNet Integrated Regional Impact Studies (IRISes), demonstrates the need for more efficient use of data resources using well-structured systems of data deposition and access. The central objective of ArcticNet's " Polar Data Management for Northern(More)
