Growth and Decay of Coral Reefs: Fifty Years of Learning describes how coral reefs have alternately flourished and declined over the last 50 years and the dynamics of these changes.
A scientific adventure story that dramatizes how profoundly our oceans have changed over the past 150 yearsIn December 1872, HMS Challenger embarked on the first round-the-world oceanographic expedition.
Die verborgene Schönheit der WeltmeereVon den eisigen Ozeanen unserer Pole bis hin zu abgelegenen Koralleninseln – der weltbekannte Naturforscher David Attenborough erkundet zusammen mit Colin Butfield die letzte große Wildnis unserer Erde: die Ozeane.
The Brazilian coral reefs form structures significantly different from the well-known reef models, as follows: they have a growth form of mushroom-shaped coral pinnacles called "e;chapeiroes"e;; they are built by a low diversity coral fauna rich in endemic species, with most of them relic forms dating back to the Miocene; and the nearshore bank reefs are surrounded by siliciclastic sediments.
Technological improvements have greatly increased the ability of marine scientists to collect and analyze data over large spatial scales, and the resultant insights attainable from interpreting those data vastly increase understanding of poplation dynamics, evolution and biogeography.
This book focuses on the survey technology, post-processing technology, mapping technology and scientific application of the submarine topography and geomorphology in detail.
Losses of life and property in the United Statesand throughout the worldresulting from hydrologic hazards, including floods, droughts, and related phenomena, are significant and increasing.
Marine debris from ships and other ocean-based sources-including trash and lost fishing gear-contributes to the spoiling of beaches, fouling of surface waters and the seafloor, and harm to marine animals, among other effects.
The National Sea Grant College Program, created in 1966, has grown into a nationwide network of 30 individual Sea Grant programs located at some of the nation's top universities.
Climate theory dictates that core elements of the climate system, including precipitation, evapotranspiration, and reservoirs of atmospheric and soil moisture, should change as the climate warms, both in their means and extremes.
Recreational fishing in the United States is an important social and economic component of many marine fisheries, with an estimated 14 million anglers making almost 82 million fishing trips in 2004.

The high latitudes of the Arctic and Antarctic, together with some mountainous areas with glaciers and long-lasting snow, are sometimes called the cryosphere-defined as that portion of the planet where water is perennially or seasonally frozen as sea ice, snow cover, permafrost, ice sheets, and glaciers.
During recent years, large-scale investigations into global climate change and other highly visible issues have taken the lion's share of declining research funds.

Improved observations of the atmospheric boundary layer (BL) and its interactions with the ocean, land, and ice surfaces have great potential to advance science on a number of fronts, from improving forecasts of severe storms and air quality to constraining estimates of trace gas emissions and transport.

Recent well documented reductions in the thickness and extent of Arctic sea ice cover, which can be linked to the warming climate, are affecting the global climate system and are also affecting the global economic system as marine access to the Arctic region and natural resource development increase.
The diversity of marine life is being affected dramatically by fishery operations, chemical pollution and eutrophication, alteration of physical habitat, exotic species invasion, and effects of other human activities.

As the nation's economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena.
Hay pocas fronteras restantes en nuestro planeta, pero quizás las más salvajes y menos entendidas son los océanos: demasiado grandes para la policía y sin una autoridad internacional clara, estas inmensas regiones de aguas traicioneras albergan la criminalidad y la explotación desenfrenadas.
