Climate change is rapidly transforming ocean conditions. Rising temperatures and shifting currents are disrupting ecosystems and causing marine species to move in new and often unpredictable ways. Coastal communities are affected by changes to coastlines, weather patterns, and access to marine resources, among other impacts. Marine protected areas (MPAs) are already experiencing the effects of climate change and managers must prepare for ongoing and future changes.

As ocean temperatures set new heat records, coral reef scientists are on a mission to identify which species and reefs can tolerate heat stress the best. But how and why do some corals cope with heat extremes better than others?

Length-weight parameters assist in the estimation of a fish’s biomass based upon assessment of length, providing value to many scientific and management applications. Some fish species have many sets of parameters published, while those less commonly studied may have no available information, making it challenging to decide which values to use. To address this, we present a database of quality-controlled length-weight parameters for 1,308 Pacific coral reef fish species from 87 families.

Global calls for greater ocean protection have sparked renewed interest in very large marine protected areas (VLMPAs, >100,000 km2) to achieve management targets; however, their conservation value is debated.

Today the world faces three interconnected crises: biodiversity loss, climate change, and unsustainable debt, each greatly exacerbating the other. Governments, Non-Governmental Organizations (NGOs), and Development Finance Institutions (DFIs) have increasingly focused on using commercial debt refinancing to simultaneously take action in support of conservation, build resilience to environmental change, and reduce or reprofile sovereign debt.

Crown-of-thorns seastars (COTS, Acanthaster spp.) are the most notorious coral predators, whose devastating outbreaks cause recurrent and extensive coral depletion across Indo-Pacific reefs. However, the spread potential of COTS outbreaks and the anthropogenic role in their initiation have remained a subject of intense debate for over five decades.

This study seeks to shed light on the rates and drivers of tree cover loss in island catchments focusing on a case study from Fiji. Global Forest Watch (GFW) is critically assessed as a framework for quantifying terrestrial tree cover loss and associated forest carbon stocks. The study assesses the role of the drivers of tree cover loss identified by GFW global models including anthropogenic deforestation: shifting agriculture, wildfires, urbanisation and plantation forestry as well as other drivers outside of the globally standardised list.

The  Blue  Carbon  Finance  Toolbox  aims  to  provide  the  global  blue  carbon  community  with  an  overall  guide  to  understanding  and  leveraging  finance  mechanisms  that  support  the  conservation,  restoration,  and  sustainable  management    of    blue    carbon    ecosystems.

If the ocean was a state of its own, it would be the seventh largest economy in the world – with a “gross marine product” of at least US$ 2.5 trillion per year. This Blue Economy is underpinned by diverse ecosystems that provide valuable services to the world, be it fishing, tourism or shipping. On the one hand, the ocean is undoubtedly an important part of the world economy. On the other hand, its asset base, that is to say its capital, is steadily declining. This is because the sea is a commons.
