September 2024: mighty krill poo, golden rules for sustainable fishing, and sea-level rise in focus at the UN.
UN Ocean Decade
The UN Decade of Ocean Science for Sustainable Development will deliver the science we need for the ocean we want.
Here’s our round-up of some of this month’s exciting ocean science news!
Antarctic krill can lock away similar levels of carbon as seagrass and mangroves
Research led by Dr Emma Cavan from Imperial College London found that a single species – the Antarctic krill, along with their poo – stores similar amounts of carbon to key ‘blue carbon’ habitats such as mangroves, saltmarshes, and seagrasses.
The study’s authors highlighted that, just like these coastal ecosystems, krill are also impacted by climate change and should be considered for similar protections.
11 golden rules to rethink fisheries policy and practice
30 international experts called for a redefinition of sustainable fishing and put forward 11 “golden rules” to?help achieve their overarching vision, which is that marine fisheries should minimise the ecological impact of every fish caught and maximise its societal benefit.
These rules are based on two guiding principles:

The UN gathers world leaders for urgent action on sea-level rise
On 25 September, as part of the United Nations General Assembly, Heads of State and Government met with experts to accelerate solutions to address?sea-level rise. The High-Level Meeting on Sea-Level Rise was the first of its kind, and?signals an increased focus from the global community on the issue.
During the meeting, the UN Secretary-General António Guterres?stressed the need for “drastic action” to reduce emissions to limit sea-level rise and to save lives. He said everyone, everywhere must be protected by early warning systems by 2027, in line with?the UN Early Warnings For All initiative.
The leaders of small island nations, which are among the most vulnerable to climate change,?united to sound the alarm on sea-level rise.
Wavel Ramkalawan, President of Seychelles, called for decisive action on climate change, adding that “it is a choice – conscious, and intentional – to continue down this path and decide that business-as-usual in pursuit of short-term gains, is acceptable.”
José Maria Pereira Neves, President of Cabo Verde, highlighted that the challenge of sea-level rise “affects all continents and regions, leaving no one immune to this catastrophe in the making.”
Both President Ramkalawan and President Pereira Neves are Patrons of the Ocean Decade Alliance, a network of eminent partners of the Ocean Decade that can catalyse support for the Decade through resource mobilisation, networking, and influence.

2 个月El océano es maravilloso, descubrir sus profundidades , una aventura. Muy pronto comenzaremos a difundir sobre Argentina Oceánica, en el marco del Decenio. El Atlantico sur y sus profundos y fríos azules, con especies unicas, a las que debemos proteger, regular su captura , comprometer a la sociedad a tener una mirada al mar, para cuidarlo.

5 个月Um dos problemas que temos, que a maioria tem, é a análise apenas superficial sobre quase tudo. Piorou com a Internet, ela traz muitas informa??es, excesso talvez, a maior parte incompleta ou errada e que cria uma dependência nas pessoas, principalmente nas novas gera??es, deprecisam consultar ferramentas de pesquisa para tudo. Perdeu-se o olhar mais detalhado, onde olhar para os detalhes era fundamental para entender o todo, ou entender o todo para perceber alguns detalhes. N?o é diferente para o krill e seus servi?os para o meio ambiente, ou para um elefante e uma manada se deslocando em busca de água. Refletir exige tempo, a sociedade está criando costumes de consumo cada vez mais impregnantes, querendo explicar que o tempo n?o é uma unidade física e cultural, mas um produto de consumo que você n?o consegue administrar, também cultural. O olhar é t?o superficial que n?o aprofunda em nada, pois, se precisar "...dou um google e me intero mais...", provavelmente com informa??es enganosas e cheias de erros, transformando tudo em verdade, até mesmo o que nem existe! Os resumos da postagem s?o bem interessantes e trazem à tona assuntos que podem mudar nosso comportamento, ou pelo menos a forma de pensar sobre eles. Parabéns!
Food for thought! There is that oft asked question by exasperated Antarctic newcomers who must listen to one more lecture aboard their ship about this ubiquitous small shrimp: "What's really the big deal about krill? Why krill?" Well take a look at this article to see krill take center stage once again at the United Nations no less. What happens to them affects all of us including the Eastern Pacific Corridor.
