Natural Resources Research Institute
The Natural Resources Research Institute (NRRI) is a United States (U.S.) based research institute founded by the Minnesota state legislature within the University of Minnesota Duluth. NRRI is a non-profit, applied research organization, established with a mission to improve the economy of Minnesota. The Institute aims to help launch small businesses and provides ongoing research and development assistance. History The mid- to late-1970s and early-1980s were particularly difficult times for Minnesota's natural resource-based industries, especially for the taconite mining industry. In the face of a domestic steel crisis, shipments of iron ore from Northeastern Minnesota's eight taconite plants plummeted. Growth in the taconite industry, which had begun in the 1950s, ended and employment in this critical base industry dropped from about 16,000 to 3,000. About 2,000 supply companies on the Iron Range, in Duluth and elsewhere in the state were also critically impacted. Perhaps no ...

Stormwater Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to '' channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry human-made cont ...

Paleolimnology
Paleolimnology (from Greek: παλαιός, ''palaios'', "ancient", λίμνη, ''limne'', "lake", and λόγος, ''logos'', "study") is a scientific sub-discipline closely related to both limnology and paleoecology. Paleolimnological studies focus on reconstructing the past environments of inland waters (e.g., lakes and streams) using the geologic record, especially with regard to events such as climatic change, eutrophication, acidification, and internal ontogenic processes. Paleolimnological studies are mostly conducted using analyses of the physical, chemical, and mineralogical properties of sediments, or of biological records such as fossil pollen, diatoms, or chironomids. History Lake ontogeny Most early paleolimnological studies focused on the biological productivity of lakes, and the role of internal lake processes in lake development. Although Einar Naumann had speculated that the productivity of lakes should gradually decrease due to leaching of catchment soils, ...

Duluth Complex
The Duluth Complex, the related Beaver Bay Complex, and the associated North Shore Volcanic Group are rock formations which comprise much of the basement bedrock of the northeastern part of the U.S. state of Minnesota in central North America. The Duluth and Beaver Bay complexes are intrusive rocks formed about 1.1 billion years ago during the Midcontinent Rift; these adjoin and are interspersed with the extrusive rocks of the North Shore Volcanic Group produced during that same geologic event. These formations are part of the Superior Upland physiographic region of the United States, which is associated with the Laurentian Upland of the Canadian Shield, the core of the North American Craton. Location The Duluth Complex includes much of Minnesota's Arrowhead Region north of Lake Superior. From the west near Duluth, Minnesota, it arcs north and northeast to about 48° north latitude south of Knife Lake, proceeds east at that latitude some five to twenty kilometers distant from a ...
