“…Because CO 2 is considerably more soluble than CH 4 in seawater, CO 2 bubbles dissolve faster and do not reach the same height in the water column as a CH 4 bubble plume with a comparable bubble size distribution. However, CO 2 bubbles have been observed to rise higher than previously expected, potentially due to the gas exchange allowing other, less-soluble gases to enter the bubble as the CO 2 dissolves into the surrounding water [41]. Thus, chemical verification is recommended in addition to visual inspection of acoustic echograms to unambiguously differentiate between the two substances.…”

“…However, a range of marine system models have been developed to describe both physical flow (ocean currents and tidal effects) and biogeochemical systems, including carbonate chemistry. Specialist models may be used to describe leak-related features, such as bubble plume dynamics [41,60]. For CCS, marine models contribute to the baseline by providing complementary information about natural variability where observational data are lacking or incomplete.…”

Carbon capture and storage (CCS) could significantly contribute to reducing greenhouse gas emissions and reaching international climate goals. In this process, CO2 is captured and injected into geological formations for permanent storage. The injected plume and its migration within the reservoir is carefully monitored, using geophysical methods. While it is considered unlikely that the injected CO2 should escape the reservoir and reach the marine environment, marine monitoring is required to verify that there are no indications of leakage, and to detect and quantify leakage if it should occur. Marine monitoring is challenging because of the considerable area to be covered, the limited spatial and temporal extent of a potential leakage event, and the considerable natural variability in the marine environment. In this review, we summarize marine monitoring strategies developed to ensure adequate monitoring of the marine environment without introducing prohibitive costs. We also provide an overview of the many different technologies applicable to different aspects of marine monitoring of geologically stored carbon. Finally, we identify remaining knowledge gaps and indicate expected directions for future research.

At the New England shelf break, cold, less saline shelf water collides with warmer saltier slope water to form a distinct oceanographic front. During the Office of Naval Research Sediment Characterization Experiment in 2017, the front was mapped by narrowband (18 and 38 kHz) and broadband (70–280 kHz) shipboard echo sounders. The acoustically determined cross-shelf velocity of the front ranged in amplitude from 0.02 to 0.33 m/s. Acoustic surveys revealed aggregations of scatterers near the foot of the front. Acoustic backscatter in conjunction with Northeast Fisheries Science Center bottom trawl surveys identified longfin squid ( Doryteuthis pealeii) and mackerel ( Scomber scombrus) as the most likely scatterers in the aggregations. A mixed species scattering model was developed and further refined by the use of a matching method used for distribution of the lengths of each species. The mean length of squid and mackerel, respectively, using the matching method was 4.45 ± 1.00 and 20.25 ± 1.25 cm compared with 6.17 ± 2.58 and 22.76 ± 1.50 cm from the trawl data. The estimated total biomass of the aggregation was a factor of 1.64 times larger when using the matching method estimated length distribution compared to the trawl length distribution.
