DESCRIPTORS *Adventure Education; *Outdoor Activities; *Recreation; *Tourism; *Travel IDENTIFIERS *Alaska; *Wilderness ABSTRACT This article provides an overview of trip programming in klaska for those seeking a low-cost wilderness adventure. Alaska is a land of glaciers, mountains, lakes, rivers, forests, and wildlife. Safety is a major concern when traveling in Alaska. A local guide or outdoor educator can assist with safety and logistical planning. Travelers should plan to spend at least 2 weeks in Alaska. July and August are the most popular months to visit the state. Lodging, rentals, and some fresh foods are more expensive than in the rest of the country, although gas, outdoor equipment, and food staples are about the same as in the rest of the country. Public transportation includes the Alaska Railroad, buses, airlines, and the Alaska Marine Highway System. The paper lists specific low-cost wilderness trips in the following areas:(1) backpacking and ski touriAg;(2) trekking and ski touring;(3) mountain biking;(4) climbing and alpine ski touring;(5) river running and flatwater touring; and (6) sea kayaking. The paper recommends 26 trips, with a brief description and the number of days to be allotted for each. -

Constant commercial fishing for groundfish has occurred since the 1960s. The implementation of areas closed to bottom trawling to protect critical habitat for fish or crabs resulted in successful management of these fisheries. The efficacy of these closures on non-target species is unknown. This study determined if differences in abundance, biomass, diversity and evenness of dominant fish and invertebrate species occur among areas open and closed to bottom trawling in the eastern Bering Sea between 1996 and 2000. -

Science Focus: Dead Zones
SCIENCE FOCUS: DEAD ZONES Creeping Dead Zones This is not the title of a sequel to a Stephen King novel. "Dead zones" in this context are areas where the bottom water (the water at the sea floor) is anoxic — meaning that it has very low (or completely zero) concentrations of dissolved oxygen. These dead zones are occurring in many areas along the coasts of major continents, and they are spreading over larger areas of the sea floor. Because very few organisms can tolerate the lack of oxygen in these areas, they can destroy the habitat in which numerous organisms make their home. The cause of anoxic bottom waters is fairly simple: the organic matter produced by phytoplankton at the surface of the ocean (in the euphotic zone) sinks to the bottom (the benthic zone), where it is subject to breakdown by the action of bacteria, a process known as bacterial respiration. The problem is, while phytoplankton use carbon dioxide and produce oxygen during photosynthesis, bacteria use oxygen and give off carbon dioxide during respiration. The oxygen used by bacteria is the oxygen dissolved in the water, and that’s the same oxygen that all of the other oxygen-respiring animals on the bottom (crabs, clams, shrimp, and a host of mud-loving creatures) and swimming in the water (zooplankton, fish) require for life to continue. The "creeping dead zones" are areas in the ocean where it appears that phytoplankton productivity has been enhanced, or natural water flow has been restricted, leading to increasing bottom water anoxia. If phytoplankton productivity is enhanced, more organic matter is produced, more organic matter sinks to the bottom and is respired by bacteria, and thus more oxygen is consumed.
