As interest in natural capital grows and society increasingly recognizes the value of biodiversity, we must discuss how ecosystem observations to detect changes biodiversity can be sustained through collaboration across regions sectors. However, there are many barriers establishing sustaining large-scale, fine-resolution observations. First, comprehensive monitoring data on both possible anthropogenic factors lacking. Second, some situ cannot systematically established maintained locations. Third, equitable solutions sectors countries needed build a global network. Here, by examining individual cases emerging frameworks, mainly from (but not limited to) Japan, illustrate ecological science relies long-term neglecting basic our home planet further reduces chances overcoming environmental crisis. We also techniques opportunities, such as DNA citizen well using existing forgotten sites monitoring, that help overcome difficulties at large scale with fine resolution. Overall, this paper presents call action for joint factors, systematic establishment maintenance observations, network, beyond cultures, languages, economic status. hope proposed framework examples Japan serve starting point discussions collaborations among stakeholders multiple society. It is time take next step detecting socio-ecological systems, if observation made more feasible, they will play an even important role ensuring sustainability future generations.

The water column of the deep ocean is dark, cold, low in food, and under crushing pressures, yet it full diverse life. Due to its enormous volume, this mesopelagic zone home some most abundant animals on planet. Rather than struggling survive, they thrive—owing a broad set adaptations for feeding, behavior, physiology. Our understanding these constrained by tools available exploring sea, but tool kit expanding along with technological advances. Each time we apply new method depths, gain surprising insights about genetics, ecology, physiology, diversity, dynamics change. These discoveries show structure within seemingly uniform habitat, limits inexhaustible resources, vulnerability impervious environment. To understand midwater need reimagine rules that govern terrestrial ecosystems. By spending more at depth—with whatever are available—we can fill knowledge gaps better link ecology environment throughout column.

The 2022 Global Deep-Sea Capacity Assessment is a baseline assessment of the technical and human capacity for deep-sea exploration research in every coastal area with deep ocean worldwide. From 200 to nearly 11,000 meters below sea level, encompasses single largest—and arguably most critical—biosphere on Earth. Globally, two-thirds all exclusive economic zones combined have water depths between 2,000 6,000 meters, making this particularly critical depth range access.

Our novel approach reveals gaps mesophotic, rariphotic, abyssal depths an underrepresentation high protection levels across all depths. In contrast, 3D footprint covers depths, with benthic fishing occurring down lower bathyal mesopelagic peaking areas overlying Additionally, efforts are biased towards where lowest pressures occur, compromising effectiveness network.

Abstract The frozen elements of the high North are thawing as region warms much faster than global mean. dangers sea level rise due to melting glacier ice, increased concentrations greenhouse gases from permafrost, and alterations in key latitude physical systems spurred many authors, more recently international agencies supra-state actors, investigate “emergency measures” that might help conserve North. However, efficacy feasibility these ideas remains highly uncertain, some come with significant risks, or could be even outright dangerous ecosystems people To date, no review has evaluated all suggested schemes. objectives this first phase literature survey (which can found a separate compendium ( https://doi.org/10.5281/zenodo.10602506 ), consider proposed interventions common evaluation space, identify knowledge gaps active conservation proposals.
