Oceans and Marine Life

sea waves

Oceans are an essential part of our planet. They provide us with food to eat and keep our atmosphere healthy. Without the oceans, we simply wouldn’t exist. But climate change means that ocean temperatures are increasing, icebergs are melting, and sea levels are rising. We need action to reverse these trends, and raising awareness is the first step. To do so, FAO hosted an online discussion titled Talking Oceans and Climate Change.

To better understand the mysteries of the world’s oceans, a team of scientists is using satellite imaging to map out, in unprecedented detail, one of the planet’s most iconic underwater ecosystems: the shallow coral reef.

The Ocean Decade will harness, stimulate and empower interdisciplinary ocean research at all levels, to support the timely delivery of the data, information and knowledge needed to achieve a well-functioning ocean in support of all SDGs of the 2030 Agenda.

Lack of funding is hampering the development of marine research and its valuable applications, according to a report published by UNESCO’s Intergovernmental Oceanographic Commission.

The IMO course in the Philippines introduced participants to the key features of marine biology and environmental impacts of invasive species.

The mesopelagic zone of the ocean, between 200 and 1 000 metres down, is where lanternfish often group together, forming dense layers. In fact, these layers contain so many fish tightly packed together that they can actually reflect sonar beams. For many years, oceanographers believed that the layers of fish were actually the ocean bottom! This is just one misconception proving how important it is to know about the sea life inhabiting the ocean depths. FAO’s illustrated guide helps scientists and researchers identify the fish in the ocean’s mesopelagic zone.

UNEP has created immersive digital experiences for its #WildforLife campaign. These four ecosystem-based “journeys” show the magic of interconnected natural systems and inspire people to take action to protect these distinct ecosystems. The first is Marine Journey. This aquatic adventure informs and inspires people to conserve coral reef, seagrass and mangrove ecosystems. The campaign aims at reversing trends such as two-thirds of oceans being significantly and negatively altered by human activity.

Join UNEP’s Wild for Life virtual, immersive journey through three unique but connected marine ecosystems – mangroves, seagrass and coral reefs – that are threatened by human activity.

The health of the oceans is tied to our health. They provide most of the oxygen we breathe. They are a major source of food and medicine and they are our allies against the coronavirus. These are just some multiple reasons why we should celebrate World Oceans Day every June 8 - to remind everyone of the major role the oceans have in everyday life. This year, under the theme “Innovation for a Sustainable Ocean”, UN will host a full-day virtual event that will shed light on innovations from around the globe. Join the UN Secretary General, experts and celebrities.

A ‘blue’ economy implies some measure of alignment between economic development and the health of the ocean. UNDP helps Seychelles, consisting of about 115 islands, strike that balance.

UNEP partner, Ocean Agency, invites parents and children to experience the ocean and its astounding life forms from their homes. Remote diving is the new remote working.
