“…Impact on benthic macrofauna, in terms of both number of species (biodiversity) and number of individuals (mortality and emigration) was significant towards the end of the 37 day injection period, but recovery of both chemical parameters and biological communities was rapid, within a few weeks Widdicombe et al, 2015). No impacts were seen on caged surface megafauna near the release site (Pratt et al, 2015) nor on the behaviour of mobile surface megafauna over the release site indicating some short term resilience in the selected species for this limited release. Microbial gene expression seemed to be the most sensitive biologically related parameter, with significant but small impacts up to 25m from the release epicentre and slight disruption to the microbially mediated nitrogen cycle .…”

This paper reviews research into the potential environmental impacts of leakage from geological storage of CO 2 since the publication of the IPCC Special Report on Carbon Dioxide Capture and Storage in 2005. Possible impacts are considered on onshore (including drinking water aquifers) and offshore ecosystems. The review does not consider direct impacts on man or other land animals from elevated atmospheric CO 2 levels. Improvements in our understanding of the potential impacts have come directly from CO 2 storage research but have also benefitted from studies of ocean acidification and other impacts on aquifers and onshore near surface ecosystems. Research has included observations at natural CO 2 sites, laboratory and field experiments and modelling. Studies to date suggest that the impacts from many lower level fault-or well-related leakage scenarios are likely to be limited spatially and temporarily and recovery may be rapid. The effects are often ameliorated by mixing and dispersion of the leakage and by buffering and other reactions; potentially harmful elements have rarely breached drinking water guidelines. Larger releases, with potentially higher impact, would be possible from open wells or major pipeline leaks but these are of lower probability and should be easier and quicker to detect and remediate.

“…2). For the most part, experiments have been conducted in the laboratory, although some studies have examined population-specific differences in gene expression across natural pH gradients in the field, illuminating how long term adaptation or acclimatization has impacted the transcriptome [23,44,78,79,87]. In addition, some studies have investigated organismal responses to acidifying conditions across two or more generations, providing further insight into the extent of phenotypic plasticity in an OA context [55,80,88,89].…”

Ocean acidification promotes broad transcriptomic responses in marine metazoans: a literature survey

2020

For nearly a decade, the metazoan-focused research community has explored the impacts of ocean acidification (OA) on marine animals, noting that changes in ocean chemistry can impact calcification, metabolism, acid-base regulation, stress response and behavior in organisms that hold high ecological and economic value. Because OA interacts with several key physiological processes in marine organisms, transcriptomics has become a widely-used method to characterize whole organism responses on a molecular level as well as inform mechanisms that explain changes in phenotypes observed in response to OA. In the past decade, there has been a notable rise in studies that examine transcriptomic responses to OA in marine metazoans, and here we attempt to summarize key findings across these studies. We find that organisms vary dramatically in their transcriptomic responses to pH although common patterns are often observed, including shifts in acid-base ion regulation, metabolic processes, calcification and stress response mechanisms. We also see a rise in transcriptomic studies examining organismal response to OA in a multi-stressor context, often reporting synergistic effects of OA and temperature. In addition, there is an increase in studies that use transcriptomics to examine the evolutionary potential of organisms to adapt to OA conditions in the future through population and transgenerational experiments. Overall, the literature reveals complex organismal responses to OA, in which some organisms will face more dramatic consequences than others. This will have wide-reaching impacts on ocean communities and ecosystems as a whole.

“…OTUs were then taxonomically classified using BLASTn against the Silva database version 108 (Pruesse et al, 2007) using the Quantitative Insights into Molecular Ecology (QIIME) pipeline (Caporaso et al, 2010). This resulted in a total of 130794 sequences (varying between 1307 and 5549 sequenced per sample) and 20682 operational taxonomic units (OTUs) (varying between 634 and 2448 OTUs per sample).…”
