Oceans & Seas

Oceans and seas play a vital role in the context of Sustainable Development Goals (SDGs) as they significantly contribute to the Earth's biosphere's health and the global economy. They are critical to sustaining life on earth, acting as a major source of food and oxygen while also serving as natural carbon sinks that mitigate climate change impacts. SDG 14, "Life Below Water," explicitly acknowledges the importance of conservation and the sustainable use of the world's oceans, seas, and marine resources.

Oceans absorb about 30% of carbon dioxide produced by humans, buffering the impacts of global warming. However, this process has implications such as ocean acidification, negatively impacting marine biodiversity and ecosystems. These impacts, coupled with unsustainable fishing practices and pollution, threaten the health of our oceans and seas. SDG 14 sets targets to prevent and reduce marine pollution of all kinds, sustainably manage and protect marine and coastal ecosystems, and regulate harvesting and end overfishing to restore fish stocks to sustainable levels.

Oceans also support economic wellbeing. Over three billion people depend on marine and coastal biodiversity for their livelihoods. By protecting oceanic ecosystems, the SDGs also support SDG 1, "No Poverty," and SDG 8, "Decent Work and Economic Growth." Furthermore, the oceanic routes are critical for global trade, supporting SDG 9, "Industry, Innovation, and Infrastructure."

Furthermore, by implementing strategies for cleaner and more sustainable use of oceans and seas, it can also contribute to SDG 13, "Climate Action." For instance, developing and implementing new technologies to harness energy from waves and tides can promote renewable energy usage and reduce reliance on fossil fuels, aligning with SDG 7, "Affordable and Clean Energy."

This chapter aligns with Goal 14: Life Below Water and Goal 13: Climate Action by exploring the potential of marine renewables, including wind, wave, and solar, for providing long-term sustainable energy sources.
An article focused on (i) understanding how climate change is decreasing ocean biodiversity and (ii) identifying the planetary health impacts accelerated by ocean biodiversity erosion.
Authors measure nutrient content in coral reef fishes in Seychelles and show that reef fish are important sources of selenium and zinc and contain levels of calcium, iron, and omega-3 fatty acids comparable with other animal-source foods.

Farmed fish are commonly exposed to stress in intensive aquaculture systems, often leading to immune impairment and increased susceptibility to disease. Effects of two aquaculture-relevant early-life stressors on the gut and skin microbiome of Atlantic salmon fry (four months post hatching) using 16S rRNA amplicon sequencing were studied.
In order to address the impacts of climate change, this manuscript presents a strategy developed to create a central resource, database and web-based platform to integrate data and information on the drivers and the changes within Guyana coastal and marine environment.

COP26 is the 2021 United Nations annual climate change conference. COP stands for Conference of the Parties. Parties are the signatories of the United Nations Framework Convention on Climate Change (UNFCCC) - a treaty agreed in 1994 which has 197 Parties (196 countries and the EU). The 2021 conference, hosted by the UK, together with our partners Italy, in Glasgow, will be the 26th meeting of the Parties, which is why it's called COP26.

Aquatic foods are increasingly being recognized as having an important role to play in an environmentally sustainable and nutritionally sufficient food system. Proposals for increasing aquatic food production often center around species, environments, and ambitious hi-tech solutions that mainly will benefit the 16% of the global population living in high-income countries.
Coral reefs worldwide are facing impacts from climate change, overfishing, habitat destruction, and pollution. The cumulative effect of these impacts on global capacity of coral reefs to provide ecosystem services is unknown. Here, we evaluate global changes in extent of coral reef habitat, coral reef fishery catches and effort, Indigenous consumption of coral reef fishes, and coral-reef-associated biodiversity. Global coverage of living coral has declined by half since the 1950s.

The Physical Oceanography of the Arctic Mediterranean Sea, Exploration, Observations, Interpretations, 2022, Pages 433-477

This book chapter advances SDG 14 by explaining the significant change in the exploration, study, and understanding of the oceanography of the Arctic Mediterranean. The first SCISEX cruise with USS Pargo 1993 indicated that the salinity and temperature in the upper layer of the Eurasian Basin were higher than previously reported, while the upper layer salih upward-looking sonars, and when the newly observed thicknesses were compared with those measured 30 years earlier, they indicated that the mean ice thickness had been reduced by about 40%. Suddenly change rather than constancy became the focus, and observations spread over time, which previously had been used to describe the mean circulation and the mean state, now acquired a time dimension.

Since the launch of the United Nations (UN) Sustainable Development Goals (SDGs) in 2015, the SDGs have been widely adopted by governments and corporations in an effort to improve their sustainability. There are 17 SDGs, comprising 169 targets, which are measurable against 247 unique indicators. Despite pervasive global pollution from (micro)plastics, there is only one indicator (14.1.1b) under Goal 14, specifically related to reducing impacts from (micro)plastics.
