Genetic variants of the coral Acropora cervicornis linked to elevated nutrient and heat stress resistance

A recent study by scientists at the University of Miami’s Rosenstiel School of Marine, Earth and Atmospheric Science, the Cooperative Institute of Marine and Atmospheric Studies (CIMAS), and NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) identified genetic variants in staghorn coral, Acropora cervicornis, that can tolerate elevated temperatures and nutrient pollution, two environmental stressors that […]

A quantitative and qualitative decision-making process for selecting indicators to track ecosystem condition

Montenero, K., Kelble, C., & Broughton, K. (2021). A quantitative and qualitative decision-making process for selecting indicators to track ecosystem condition. Marine Policy, 129, 104489.

Abstract: Ecosystem indicators are a well-established method for tracking ecosystem conditions and trends with the purpose of informing ecosystem-based management. The selection of indicators is a key step in the management process; however, because 1) selection can be inherently subjective 2) researchers can be entrenched in the ecosystem components they routinely measure, and 3) some voices may be marginalized in a group setting, the selection, prioritization, and consensus processes can be challenging. To overcome these issues, an indicator selection process was developed herein that incorporated expert opinion both qualitatively and quantitatively.

Natural and Anthropogenic Drivers of Acidification in Large Estuaries

Natural and Anthropogenic Drivers of Acidification in Large Estuaries Wei-Jun Cai, Richard A. Feely, Jeremy M. Testa, Ming Li, Wiley Evans, Simone R. Alin, Yuan-Yuan Xu, Greg Pelletier, Anise Ahmed, Dana J. Greeley, Jan A. Newton, Nina Bednaršek Annual Review of Marine Science 2021 13:1

Oceanic uptake of anthropogenic carbon dioxide (CO2) from the atmosphere has changed ocean biogeochemistry and threatened the health of organisms through a process known as ocean acidification (OA). Such large-scale changes affect ecosystem functions and can have effects on societal uses, fisheries resources, and economies. In many large estuaries, anthropogenic CO2-induced acidification is enhanced by strong stratification, long water residence times, eutrophication, and a weak acid–base buffer capacity. In this article, we review how a variety of processes influence aquatic acid–base properties in estuarine waters, including river–ocean mixing, upwelling, air–water gas exchange, biological production and subsequent respiration, anaerobic respiration, calcium carbonate (CaCO3) dissolution, and benthic inputs…

Effective Science‐Based Fishery Management is Good for Gulf of Mexico’s “Bottom Line” – But Evolving Challenges Remain

Karnauskas, M. , Allee, R. J., Craig, J. K., Jepson, M. , Kelble, C. R., Kilgour, M. , Methot, R. D. and Regan, S. D. (2019), Effective Science‐Based Fishery Management is Good for Gulf of Mexico’s “Bottom Line” – But Evolving Challenges Remain. Fisheries, 44: 239-242. doi:10.1002/fsh.10216

Introduction: The northern Gulf of Mexico (GoM) is an ecologically and economically productive system that supports some of the largest volume and most valuable fisheries in the United States. The benefit of these fisheries to society and to the surrounding Gulf communities has varied historically, commensurate with the fish population sizes and the economic activities they are able to sustain. Following reauthorization of the Magnuson‐Stevens Fishery Conservation and Management Act (MSA) as amended by the Sustainable Fisheries Act in 1996, strict requirements were put into place for rebuilding overfished stocks, including several in the GoM. Now 2 decades later, we can assess the impacts of fisheries management, as guided by the MSA and implemented by the National Oceanic and Atmospheric Administration (NOAA) Fisheries Service, the Gulf of Mexico Fishery Management Council, the Gulf States Marine Fisheries Commission and other state and international agencies. The northern GoM has experienced increases in biomass levels for many stocks, concurrent with increased commercial landings and revenues, increased recreational fishing effort, and a steadily growing regional ocean economy over the past decade (Karnauskas et al. 2017). However, it is critical to interpret these trends in the context of other major drivers in the Gulf ecosystem, and to ensure that all resource users can reap the benefits of a well‐managed fisheries system for years to come.

The Oceanic Sink for Anthropogenic CO2 from 1994 to 2007

Gruber, N., Clement, D., Carter, B. R., Feely, R. A., van Heuven, S., Hoppema, M., … & Monaco, C. L. (2019). The oceanic sink for anthropogenic CO2 from 1994 to 2007. Science, 363(6432), 1193-1199.


We quantify the oceanic sink for anthropogenic carbon dioxide (CO2) over the period 1994 to 2007 by using observations from the global repeat hydrography program and contrasting them to observations from the 1990s. Using a linear regression–based method, we find a global increase in the anthropogenic CO2 inventory of 34 ± 4 petagrams of carbon (Pg C) between 1994 and 2007. This is equivalent to an average uptake rate of 2.6 ± 0.3 Pg C year−1 and represents 31 ± 4% of the global anthropogenic CO2 emissions over this period. Although this global ocean sink estimate is consistent with the expectation of the ocean uptake having increased in proportion to the rise in atmospheric CO2, substantial regional differences in storage rate are found, likely owing to climate variability–driven changes in ocean circulation.
