2014, NYSDEC Lake Ontario Annual Report 2013-14
For almost two decades Little Galloo Island (LGI) has supported a large colony of Double-crested Cormorants (Phalacrocorax auritus) in the eastern basin of Lake Ontario. Cormorant nest counts on the island since the early 1990's have averaged 4,297 per year. However, less than 2,000 pairs have nested on the island...

Mineral resource of the month: Iron and steel
Michael D. Fenton
2014, Earth
Iron is one of the most abundant elements on Earth, but it does not occur in nature in a useful metallic form. Although ancient people may have recovered some iron from meteorites, it wasn’t until smelting was invented that iron metal could be derived from iron oxides. After the beginning...

2014, Geophysical Research Letters (41) 370-376
Here we report on deep long-period earthquakes (DLPs) newly observed in four places in western Oregon. The DLPs are noteworthy for their location within the subduction fore arc: 40–80 km west of the volcanic arc, well above the slab, and near the Moho. These “offset DLPs” occur near the top of...
Simulated and observed 2010 flood-water elevations in selected river reaches in the Moshassuck and Woonasquatucket River Basins, Rhode Island
Phillip J. Zarriello, David E. Straub, Stephen M. Westenbroek
2014, Scientific Investigations Report 2013-5191
Heavy persistent rains from late February through March 2010 caused severe flooding and set, or nearly set, peaks of record for streamflows and water levels at many long-term U.S. Geological Survey streamgages in Rhode Island. In response to this flood, hydraulic models were updated for selected reaches covering about 33...
A previously unrecognized path of early Holocene base flow and elevated discharge from Lake Minong to Lake Chippewa across eastern Upper Michigan
Walter L. Loope, Harry M. Jol, Timothy G. Fisher, William L. Blewett, Henry M. Loope, Robert J. Legg
2014, GSA Special Papers (508) 1-13
It has long been hypothesized that flux of fresh meltwater from glacial Lake Minong in North America's Superior Basin to the North Atlantic Ocean triggered rapid climatic shifts during the early Holocene. The spatial context of recent support for this idea demands a reevaluation of the exit point of meltwater...
Evaluating CO2 and CH4 dynamics of Alaskan ecosystems during the Holocene Thermal Maximum
Yujie He, Miriam C. Jones, Qianlai Zhuang, Christopher Bochicchio, B. S. Felzer, Erik Mason, Zicheng Yu
2014, Quaternary Science Reviews (86) 63-77
The Arctic has experienced much greater warming than the global average in recent decades due to polar amplification. Warming has induced ecological changes that have impacted climate carbon-cycle feedbacks, making it important to understand the climate and vegetation controls on carbon (C) dynamics. Here we used the Holocene Thermal Maximum...
