27 This work is focused on results from a recent controlled sub-seabed in situ 28carbon dioxide (CO 2 , 2005;Haszeldine, 2009; Wilkinson et al., 2013). 60 ShackleyBefore sub-sea CO 2 storage can be carried out on a commercial scale, ecological 61 consequences as well as adverse environmental and human impacts of potential CO 2 62 leakages need to be identified and reliable monitoring strategies for detection and 63 quantification of potential leakages, both acute (broken pipes, leaking connections, 64 etc.) and chronic (faults in the geological caprock), need to be developed. 65Previous efforts to study controlled CO 2 releases with the focus on environmental 66 impact and detectability were restricted by either small-scale direct injections of 67 liquid CO 2 into the deep water layers or model studies of the fate of released CO 2 . 68Small-scale liquid CO 2 injections were carried out in a series of experiments off the 69 coast of California (Brewer et al., 2003(Brewer et al., , 2004, which later developed into the FOCE 70 (Free Ocean CO 2 Enrichment) program (Kirkwood et al., 2005(Kirkwood et al., , 2009 Walz et al., 71 2008). 72Modelling studies based on natural CO 2 releases in Kagoshima Bay described 73 physico-chemical processes of CO 2 transformation in seawater (Dissanayke et al., 74 2012). Numerous models were developed to predict the behaviour of leaking CO 2 , 75 purposefully stored under the seabed (Blackford et al., 2008;Kano et al., 2010; Dewar 76 et al., 2013), and as a consequence the rise of pCO 2 (Kano et al., 2009) or the 77 transformation pathways of released CO 2 in the deep ocean (Jeong et al., 2010). 78 4 Natural marine CO 2 seepage sites, like the one off the coast of Panarea Island, 79 Southern Italy, are widely and extensively studied in terms of assessment of CO 2 80 impacts to seawater chemistry and ecology (Pearce et al., 2014). 81 Within the NERC funded research project QICS (Quantifying and Monitoring 82Potential Ecosystem Impacts of Geological Carbon Storage) a large scale controlled 83 in situ CO 2 sub-seabed release was conducted in Ardmucknish Bay, Scotland (Fig. 1) 84 in spring-summer of 2012, in order to make a realistic simulation of CO 2 leakage 85event. An overview of the physical aspects of CO 2 migration through the sediment 86 overburden and overlying water column, as well as of the ecological and 87 biogeochemical impacts on the benthos, of this experiment were recently described in 88 The CO 2 release experiment (QICS) was carried out in Ardmucknish Bay, near 109Oban on the Scottish west coast (Fig. 1, inset 132The CO 2 gas was released from a land-based container, through a 20 mm diameter 133 welded stainless steel pipeline terminating in a 5 m long diffuser with multiple 0.5 134 mm perforations located 11 m below the seabed. The overlying water depth at the 135 7 study site was 10-12 m depending on the tide. (Fig. 3a).

“…These events could become more common and more severe as the oceans absorb more CO 2 . In addition, the future use of geo-logical storage to reduce CO 2 emissions (Holloway 2005) brings with it the risk of possible leaks from pipelines and subseabed storage sites, and considerable subsequent localised impact on benthic communities even in shallow water ecosystems (Blackford et al 2009, Kano et al 2010, possibly including the intertidal zone.…”

Ocean acidification (OA) is predicted to play a major role in shaping species biogeography and marine biodiversity over the next century. We tested the effect of medium-term exposure to OA (pH 8.00, 7.30 and 6.70 for 30 d) on acid -base balance in the decapod crab Necora puber -a species that is known to possess good extracellular buffering ability during short-term exposure to hypercapnic conditions. To determine if crabs undergo physiological trade-offs in order to buffer their haemolymph, we characterised a number of fundamental physiological functions, i.e. metabolic rate, tolerance to heat, carapace and chelae [Ca 2+ ] and [Mg 2+ ], haemolymph [Ca 2+ ] and [Mg 2+ ], and immune response in terms of lipid peroxidation. Necora puber was able to buffer changes to extracellular pH over 30 d exposure to hypercapnic water, with no evidence of net shell dissolution, thus demonstrating that HCO 3 -is actively taken up from the surrounding water. In addition, tolerance to heat, carapace mineralization, and aspects of immune response were not affected by hypercapnic conditions. In contrast, whole-animal O 2 uptake significantly decreased with hypercapnia, while significant increases in haemolymph [Ca 2+ ] and [Mg 2+ ] and chelae [Mg 2+ ] were observed with hypercapnia. Our results confirm that most physiological functions in N. puber are resistant to low pH/ hypercapnia over a longer period than previously investigated, although such resistance comes at the expenses of metabolic rates, haemolymph chemistry and chelae mineralization.KEY WORDS: Ocean acidification · Physiology · Metabolic depression · Necora puber · Thermal tolerance · Carbon capture and storage Resale or republication not permitted without written consent of the publisher

“…Numerical simulation model approaches have been used to predict CO 2 behavior after leakage into the ocean (e.g. Kano et al, 2010;Dewar et al, 2013). However, it is difficult to perform enough analysis under the present conditions because the field observation data necessary for simulation model analysis of CO 2 behavior in the ocean are insufficient.…”
