UNCLOS or Law of Sea Offers Cooperation for Sustainable Oceans

The United Nations Convention on the Law of the Sea (UNCLOS) is a comprehensive UN legal policy document demarcating areas of the sea under the jurisdiction of member states as well as legal clauses for human maritime activity in a comprehensive manner. The UNCLOS aims to demarcate and scrutinize the legal ramifications in the fullest […]

Sinkholes, a fascinating feature of Earth’s Karst Topography

The action of surface water and groundwater in the chemical weathering or chemical erosion of soluble carbonate rocks such as magnesium carbonates (dolomites) and calcium carbonates (limestone) produces landforms that are called karst topography. Geological features such as caves, sinkholes, underground rivers, barren and rocky ground and lack of surface water bodies are all results […]

Coral Bleaching and Clive Wilkinson Report

The coral bleaching phenomenon The beautiful coral reefs surrounded by blue tropical seas are not just coloured rocks but are thriving ecosystems with live corals that attach their skeletons to rocks and live there. The colours indicate the presence of single-celled algae-like zooxanthellae within their tissues that provide them with the essential nutrients through photosynthesis […]

Astounding Biodiversity around Deep Sea Vents

Deep sea vents or hydrothermal vents are fissures at the sea floor out of which flows out a stream of mineral and gas-rich geothermally heated seawater. Deep sea vents are a result of sea floor spreading and are mostly found in ocean ridges. https://www.geographyandyou.com/science/beneath-ocean-ridge/ They are formed by the heating up of sea water that […]

Exclusive Economic Zone as opposed to Fishery Zone

According to the United Nations Convention on the Law of the Sea (UNCLOS), an international agreement in force since 1994 regarding international activity in the world’s oceans, Article 55 of the document defines the legal regime of the Exclusive Economic Zone. The article defines an area of ocean marked as an Exclusive Economic Zone (or […]

Exploring Regulations to Check Saline Water Ingression in India

For people living in coastal areas rivers and lakes are not ubiquitously available. They thus depend on groundwater for their needs, which leads to probabilities of saline water ingression. Groundwater close to the coast can be easily laden with salt, especially when the equilibrium between coastal aquifers and sea water is disturbed. https://www.geographyandyou.com/climate-change/water/groundwater-sustainable-irrigation/ N.C. Mondal, […]

Lagoons in India

Lagoons – Losing India’s rich biodiversity zones

Lagoons are generally divided into coastal lagoons and atoll lagoons. However, there is ambiguity over the distinction between an estuary and a lagoon. For this purpose the definitions given by Cameron and Pritchard (1963) are the most commonly accepted definitions. While an estuary is an inland river valley or coastal plain inundated by sea water […]

The Sargasso Sea – a unique ecosystem protected by seaweed

Located in the area marked under the fabled ‘Bermuda Triangle’, the Sargasso Sea located within the North Atlantic Ocean is the only sea in the world that does not have a land boundary. Unlike other seas, its location is defined using ocean currents. It lies within a large system of rotating ocean currents called the […]

Beneath the Ocean Floor | Discovery of Ocean Ridge

Ocean ridge discovery From the late 1930s, new techniques have opened up in submarine geology. Gravity measurements and geotectonic imagery have allowed accurate mapping of the sea surface and the bottom structure of the oceans. The ocean floor, far from being smooth and flat, is marked by huge mountain ranges – the mid-ocean ridge that […]
