Geologic Site of the Month: Why Is Sebago Lake So Deep?
Why is Sebago Lake so deep? Maine Geological Survey Maine Geologic Facts and Localities February, 1999 Why is Sebago Lake so deep? 43° 51‘ 13.36“ N, 70° 33‘ 43.98“ W Text by Robert A. Johnston Maine Geological Survey, Department of Agriculture, Conservation & Forestry 1 Why is Sebago Lake so deep? Maine Geological Survey Introduction Modern geophysical equipment allows geologists to investigate previously unmapped environments, including ocean and lake floors. Recent geophysical research studied the types, composition, areal extent, and thickness of sediments on the bottom of Sebago Lake in southwestern Maine. Geologists used side- scan sonar and seismic reflection profiling to map the bottom of the lake. Approximately 58 percent of the lake bottom was imaged with side-scan sonar and over 60 miles of seismic reflection profiles were collected. This web site will discuss the findings of the seismic reflection profiling. Maine Geological Survey, Department of Agriculture, Conservation & Forestry 2 Why is Sebago Lake so deep? Maine Geological Survey Physiographic setting Sebago Lake, although second in surface area to Moosehead Lake, is Maine's deepest lake. With a water depth of 316 feet, its deepest part is 49 feet below sea level! Sebago Lake is located in southwestern Maine 20 miles northwest of Portland and 50 miles southeast of the White Mountains. It lies along the transition between the Central Highlands and the Coastal Lowlands physiographic regions of New England (Figure 1). The abrupt change in landscape can be seen in panoramic views from several vantage points near Sebago Lake. Denny, 1982 Denny, Maine Geological Survey From From Figure 1. -

The Aral Sea
The Aral Sea edited by David L. Alles Western Washington University e-mail: [email protected] Last Updated 2011-11-4 Note: In PDF format most of the images in this web paper can be enlarged for greater detail. 1 Introduction The Aral Sea was once the world's fourth largest lake, slightly bigger than Lake Huron, and one of the world's most fertile regions. Today it is little more than a string of lakes scattered across central Asia east of the Caspian Sea. The sea disappeared for several reasons. One is that the Aral Sea is surrounded by the Central Asian deserts, whose heat evaporates 60 square kilometers (23 sq. miles) of water from its surface every year. Second is four decades of agricultural development and mismanagement along the Syr Darya and Amu Darya rivers that have drastically reduced the amount of fresh water flowing into the sea. The two rivers were diverted starting in the 1960s in a Soviet scheme to grow cotton in the desert. Cotton still provides a major portion of foreign currency for many of the countries along the Syr Darya and Amu Darya rivers. By 2003, the Aral Sea had lost approximately 75% of its area and 90% of its pre- 1960 volume. Between 1960 and January 2005, the level of the northern Aral Sea fell by 13 meters (~ 43 ft) and the larger southern portion of the sea by 23 meters (75.5 ft) which means that water can now only flow from the north basin to the south (Roll, et al., 2006). -
Field Identification Guide to the Sharks and Rays of the Red Sea and Gulf of Aden
FAO SPECIES IDENTIFICATION GUIDE FOR FISHERY PURPOSES ISSN 1020-6868 FIELD IDENTIFICATION GUIDE TO THE SHARKS AND RAYS OF THE RED SEA AND GULF OF ADEN PERSGA FAO SPECIES IDENTIFICATION GUIDE FOR FISHERY PURPOSES FIELD IDENTIFICATION GUIDE TO THE SHARKS AND RAYS OF THE RED SEA AND GULF OF ADEN by Ramón Bonfil Marine Program Wildlife Conservation Society Bronx, New York, USA and Mohamed Abdallah Strategic Action Program Regional Organization for the Conservation of the Environment of the Red Sea and Gulf of Aden Jeddah, Saudi Arabia FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome, 2004 iii PREPARATION OF THIS DOCUMENT This document was prepared under the coordination of the Species Identification and Data Programme of the Marine Resources Service, Fishery Resources and Environment Division, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). This field guide is largely based on material prepared for training courses on elasmobranch identification delivered in the region by the first author, and promoted by the Regional Organization for the Conservation of the Environment of the Red Sea and Gulf of Aden (PERSGA), as an activity of PERSGA’s Strategic Action Programme (SAP) towards capacity building and technical assistance in the Red Sea and Gulf of Aden region. Printing was supported by Japanese Government funds. The increasing recognition of the significance of sharks and batoid fishes as ecosystem health indicators, as well as their particular importance in exploited ecosystems in the Red Sea and the Gulf of Aden, have been key considerations to promote the preparation of this Field Guide. Furthermore, in recent years the reported catches of elasmobranchs in the Red Sea and the Gulf of Aden showed a marked increase. -

Lake level was close to a minimum 17 before approximately AD 300, at about AD 600, AD 1220 and AD 1400. Since 1960 the 18 lake level is lowering again. Lake water level was lowest during the 14th or early 15th 19 centuries as indicated by a coeval settlement, which today is still under water near the 20 well-dated mausoleum of Kerderi. -
