U. Hawaii Scientists Predict Future With More Extreme Pacific Sea Level Events

Tropical Pacific island nations already struggling to adapt to rising sea levels may also have to contend with greater fluctuations in seasonal sea levels in the future. The fluctuation risk appears linked to a change in El Niño that is forecasted to affect wind patterns in the Pacific Ocean. Researchers at the University of Hawaii are making the prediction after analyzing climate models and tide gauge data with help from others at Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO). Scientists at both institutions say that El Niño causes warm waters and higher sea levels to shift eastward around the Pacific Ocean. These understandably pull waters away from western shores.

Flood Warning Systems

Chapter Overview: Flood Warning A Real-Time Solution Streamflow Measurements Typical Flood Warning System Monitoring Location Data Management Quality Assurance Recommended Equipment Why Monitoring Matters While some areas are more prone to flooding than others, the establishment of flood warning systems near any major waterway or body of water provides critical information that can protect property and save lives. Of course, the most effective flood warning methods extend beyond the installation of gages and telemetry equipment, and employ qualified staff and carefully designed procedures to provide the earliest warning about whether a flood should be expected, when it will occur, and how severe it will be.

Study Finds Pacific Bluefin Tuna Change Distribution To Maximize Energy

Pacific bluefin tuna are listed as a threatened species, largely because their stocks have been overfished to provide for human consumption. Because of this status, they are being watched by conservation organizations and scientists looking to help restore their populations. Some of these onlookers include researchers from Stanford University, the Monterey Bay Aquarium and the National Oceanic and Atmospheric Administration who have recently completed a tracking study that has helped identify where the bluefins congregate in the Pacific Ocean during different periods throughout the year. The results of the work, they say, will help inform future conservation strategies looking to revive the fish’s numbers.

Photos: World's Five Deepest Lakes

Water is an amazing thing. It can freeze into masses of ice and float or turn into steam and drift away. But perhaps one of water’s most interesting feats is its ability to conceal. Think about it: Just standing on a shoreline, looking over a water body, there’s no way of knowing what’s under the surface at any certain point. All we can see are waves -- what do the depths hold? With that sense of wonder in mind, we’ve put together a photographic list of the world’s five deepest lakes. All of these water bodies are more than 2,700 feet deep at maximum and full of mysteries just waiting for scientists to solve. They are beautiful examples of water’s power to tuck things out of site, and we’ve listed them in order from most shallow to deepest (click to enlarge): 5.
