In the current context of global environmental change, understanding the dynamics of direct and indirect greenhouse gas (GHG; including CH4, CO2, NOx, O3, H2O vapor; HFCs, SF6) fluxes in aquatic ecosystems is critical. Along the land-ocean aquatic continuum, freshwater and coastal ecosystems including wetlands play a significant role in the global carbon cycle and climate regulation. However, many mechanisms driving GHG production, consumption, and total fluxes (particularly of the lesser […]

In support of the United Nations Decade of Ocean Sciences for Sustainable Development (2021–2030), the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS) are collaborating on a living special collection that curates and showcases the broad range of solutions-focused research that meets the Ocean Decade’s vision: “the science we need for the ocean we want.” This special collection will highlight ongoing scientific research and innovative efforts that contribute to achieving the

We are pleased to announce a call for papers for a special issue of Limnology & Oceanography Letters focusing on methane emissions from aquatic environments. Freshwater, brackish, and marine environments significantly contribute to global methane emissions, but the high degree of variability in estimates from these environments is largely responsible for the uncertainty in estimates of methane emissions from natural sources. With this special issue of Limnology & Oceanography Letters,

In a rapidly changing world, it is crucial that we examine the responses of aquatic organisms across the scales of individuals, communities, and trophic levels, on time scales relevant for responses to environmental change. Laboratory studies allow us to develop mechanistic understandings on individual organisms or groups thereof but are often limited in their ecological realism. In situ observations yield important information on environments in their current state but cannot

Expanding the Horizons of Sclerochronology: New Perspectives for Life History and Environmental Monitoring Article proposals due 30 October 2023 Manuscripts due 30 June 2024 We are pleased to announce a Call for Papers for a special issue presenting advances in sclerochronology research and its applications in aquatic systems. Sclerochronology is the study of physical, chemical and structural variations in the accretionary hard tissues of organisms, such as mollusc shells, coral

  The development and deployment of autonomous instrumentation in the aquatic sciences, which has rapidly expanded during the last decade, has led to fantastic new insight into unexplored waters, increased understanding of temporal and spatial dynamics, and amazing discoveries across the aquatic sciences. These tools have allowed us to acquire more data, at higher frequency in time and space, and at a lower cost. Sensors deployed on gliders, autonomous underwater

A general aim of microbial ecology is to observe, understand, and predict the distribution and interactions of microorganisms in the context of environmental conditions. Taxonomic profiling of different microbial communities often reveals significant but unexplained variations across aquatic environments both in space and time. Functional differences among organisms are often invoked as an explanation; and variation in gene content (assessed by metagenomics) often reveals dynamic relationships between metabolic pathways and

Microplastics and microfibers (hereafter referred to as “microplastics”) are a pressing threat to aquatic ecosystems and have been the topic of much recent research. This research has documented quantities and locations of microplastic accumulation in many marine and freshwater environments. However, an important emerging topic is the extent to which these microplastics are making their way into the aquatic organisms that inhabit these environments and the potential consequences of their
