hull cutting through water and should be tall enough to prevent water from easily washing over the top of it. On slower ships like tankers‚ a fuller bow shape is used to maximise the volume of the ship for a given length. A "wet bow" results from seawater washing over the top of the hull. A raked stem can help to reduce the wetness of the bow. Aside from making the deck slippery‚ water can corrode the metal of the ship. If the temperature is low enough this water can also freeze on the deck‚ rails

precipitation a year and another 30 percent come from the island’s 17 reservoirs. But digging further reservoirs is not feasible because space is at a premium in Singapore. Instead‚ officials have been forced to find other options. The desalination of seawater is another source of water‚ but it is cost-intensive and therefore only makes up around 10 percent of Singapore’s water supply. That led the government to launch a project called “NEWater” back in 2003. It involves recycling wastewater to highly

Introduction Over the last decade‚ there has been an increased focus on the impact of human activities on the planet and studying the potential impacts of ocean acidification (OA). Ocean acidification describes a change in the carbon chemistry of the ocean which has been a steadily emerging global environmental health concern. Oceans cover nearly 70 percent of the planet’s surface and play a crucial role in regulating atmospheric carbon dioxide through physical‚ chemical‚ and biological processes

Arctic sea ice loss Main articles: Polar ice packs and Climate change in the Arctic The decline in Arctic sea ice‚ both in extent and thickness‚ over the last several decades is further evidence for rapid climate change.[60] Sea ice is frozen seawater that floats on the ocean surface. It covers millions of square miles in the polar regions‚ varying with the seasons. In the Arctic‚ some sea ice remains year after year‚ whereas almost all Southern Ocean or Antarctic sea ice melts away and reforms

In October 2005‚ the Long Beach Seawater and Desalination Research and Development Facility was officially commissioned. It operated for four years as a research facility for a new technique for desalinization (Bradley). Half of the funding of the estimated $20 million project was from
