Using data from 1387 lakes collected over three decades, we found a wide range in the concentrations of total phosphorus (TP), total nitrogen (TN) and chlorophyll in Florida lakes, and that edaphic factors as outlined by the USEPA’s Florida Lake Regions were the dominant factor in determining the concentrations of plant nutrients in the state’s lakes. The hypothesis that all eutrophic lakes in ...

In the present study, the cyanobacterial flora of Urmia Lake (NW Iran), one of the largest salt lakes in the world and adjacent rivers is investigated. Urmia Lake comprises different micro-organisms including cyanobacteria which have a major role in aquatic ecosystems. Cyanobacterial samples were collected in 2008–09 from Urmia Lake and its surrounding ecosystems. All samples were cultivated, i...

We study the basic properties of an equally weighted index of U.S. commodities futures from the perspective of a Japanese investor. We find that the returns on the U.S. equally-weighted commodity futures index maintain their basic properties documented in Gorton and Rousenhorst (2005), when translated into Yen. In particular, looking at returns on Japanese stocks and bonds, the commodity future...

We discuss the statistical mechanics of a system of self-gravitating fermions in a space of dimension D. We plot the caloric curves of the self-gravitating Fermi gas giving the temperature as a function of energy and investigate the nature of phase transitions as a function of the dimension of space. We consider stable states (global entropy maxima) as well as metastable states (local entropy m...

“Our analysis finds Earth’s lakes are power-law distributed for lakes ≥ 8.5 km2 (Fig. 2). Lakes < 8.5 km2 deviate from the power-law distribution such that there are fewer of these small lakes than expected if small lakes conformed to the same power-law distribution as large lakes. Across the range of lake sizes conforming to a power-law distribution, the tail exponent is τ = 1.97 (+ /− 0.01), ...

Spatial and attribute database of the glaciers and glacial lakes of whole Nepal had developed by ICIMOD in collaboration with UNEP/RRC-AP in 2001 using remote sensing and geographic information systems techniques. There are altogether 3,252 glaciers covering an area of 5,322 square kilometer with approximately 481 km of ice reserves. The Mahakali River basin comprises 87 glaciers with an area o...

The stable-isotopic signature of dissolved inorganic carbon (DIC) has been routinely used in temperate lake systems to investigate the biogeochemical dynamics of carbon. We studied seven perennially ice-covered lakes in the McMurdo Dry Valleys, Antarctica, to ascertain how carbon cycling affects the dC of DIC in water columns of these systems. Unlike temperate lakes and, in fact, most polar lak...

Autonomous underwater vehicles (AUVs) are important in areas such as scientific research and resource collection. However, AUVs suffer from data portability energy problems due to their physical size limitation. In this work, an acoustic guidance method for docking is proposed solve the problem of persistent operation. A funnel station autonomous remotely operated vehicle (ARV) used platform de...
