Mangrove roots provide a perfect playground for developing fishes, like these adorable young round rays! (GIFs don’t do the cute justice—watch the video to enjoy the true power of this bouncy ballet of mini sea flap flaps! We’ve had it on repeat all afternoon.)

Cold-water corals in an era of rapid global change: are these the deep ocean’s most vulnerable ecosystems?

Cold-water corals create highly complex biogenic habitats that promote and sustain high biological diversity in the deep sea and play critical roles in deep-water ecosystem functioning across the globe. However, these often out of sight and out of mind ecosystems are increasingly under pressure both from human activities in the deep sea such as fishing […]

Acidificación del océano: ¿amenaza para la vida marina? (in Spanish)

La Acidificación de los Océanos (AO) se ha convertido junto con el cambio climático y la disminución de oxígeno en el océano, en uno de los principales agentes de presión ambiental. Por lo tanto, se requiere de un apoyo importante de la comunidad académica y científica para tratar de evaluar y determinar cuáles son los […]

Survey of Cnidarian gene expression profiles in response to environmental stressors: summarizing 20 years of research, what are we heading for?

Coral research has come a long way since the pioneering coral biology studies of thermal tolerance dating back to the turn of the previous century. In great contrast, at the present time, the currently available in silico technologies enable the entire transcriptome to be surveyed in a high-throughput manner following an array of stress manipulations.

Sea surface pCO2 and its variability in the Ulleung Basin, East Sea constrained by a neural network model

Currently available surface seawater partial pressure carbon dioxide () data sets in the East Sea are not enough to quantify statistically the carbon dioxide flux through the air-sea interface. To complement the scarcity of the measurements, we construct a neural network (NN) model based on satellite data to map for the areas, which were not […]

Adaptive capacity of the sea urchin Heliocidaris erythrogramma to ocean change stressors: responses from gamete performance to the juvenile

To predict impacts of ocean acidification and warming on the responses of marine populations, it is important to determine an organism’s capacity for phenotypic plasticity and genetic adaptation. We determined the effects of near-future...Show More Summary

Evaluating the effects of diel-cycling hypoxia and pH on growth and survival of juvenile summer flounder Paralichthys dentatus

Effects of diel-cycling dissolved oxygen (DO) and pH on young-of-the-year summer flounder Paralichthys dentatus were examined in laboratory experiments. Flounder were exposed to 2 cycling DO levels (extreme = 1-11 mg O2 l-1; moderate = 3-9 mg O2 l-1), 2 cycling pH levels (extreme = 6.8-8.1; moderate = 7.2-7.8), and static normoxia (7.5 mg O2 […]

This extremely long spine on procelain crab is important for lateral swimming, improves their swimming ability, helping them to remain in coastal water, where soon it will develop into a mature porcalain crab.

Who say you need the cover of darkness to be sneaky? The day octopus spends the workday hunting, staying stealthy by transforming its skin texture to mimic nearby corals, rocks or algae.

Parasitic infection: a missing piece of the ocean acidification puzzle

Ocean acidification (OA) research has matured into a sophisticated experimental and theoretical scientific discipline, which now utilizes multiple stressor, mesocosm experiments, and mathematical simulation models to predict the near-future effects of continued acidification on marine ecosystems.

Study links altered brain chemistry, behavioral impairments in fish exposed to elevated carbon dioxide

Research team studied damselfish behavior, physiology under ocean acidification conditions predicted for year 2300. MIAMI—In a first-of-its-kind study, researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric...Show More Summary

Altered brain ion gradients following compensation for elevated CO2 are linked to behavioural alterations in a coral reef fish

Neurosensory and behavioural disruptions are some of the most consistently reported responses upon exposure to ocean acidification-relevant CO2 levels, especially in coral reef fishes. The underlying cause of these disruptions is thought to be altered current across the GABAA receptor in neuronal cells due to changes in ion gradients (HCO3? and/or Cl?) that occur in […]

Why the EPA doesn’t regulate ocean acidification

Imagine that a recently discovered pollutant prevented trees from forming leaves. Every April, buds would spring from the branches, and kids on their way to school would point to the tiny shoots of green and pink. But as the leaves fleshed out further and began to photosynthesize, an invisible vapor would choke and corrode them. […]

Frontiers in Marine Science: invitation to submit research articles on the topic “Coral Reef Calcification in a Changing Ocean: from Microscale Mechanisms to Macroscale Responses”

Coral reefs are among the most biologically diverse and economically important ecosystems on the planet. However, anthropogenic CO2 emissions are driving unprecedented changes in the tropical oceans, where the vast majority of shallow water reefs exist. Show More Summary

Concomitant ocean acidification and increasing total alkalinity at a coastal site in the NW Mediterranean Sea (2007-2015)

Monitoring of global ocean change is necessary in coastal zones due to their physical and biological complexity. Here, we document changes in coastal carbonate chemistry at the coastal time-series station, Point B, in the NW Mediterranean Sea from 2007 through 2015 at 1 and 50?m. The rate of surface ocean acidification (?0.0028?±?0.0003 units pHT?yr?1) was […]

Using present-day observations to detect when anthropogenic change forces surface ocean carbonate chemistry outside preindustrial bounds (update)

One of the major challenges to assessing the impact of ocean acidification on marine life is detecting and interpreting long-term change in the context of natural variability. This study addresses this need through a global synthesis of monthly pH and aragonite saturation state (?arag) climatologies for 12 open ocean, coastal, and coral reef locations using […]
