We describe RAPID: a Real-time Automated Plankton Identification Dashboard, deployed on the Imager, high-speed line-scan camera that is connected to ship water supply and captures images of particles in flow-through system. This end-to-end pipeline for zooplankton data uses Edge AI equipped with classification (ResNet) model separates into three broad classes: Copepods, Non-Copepods Detritus. The results are transmitted visualised terrestrial system near real time. Over 7-days survey, Imager successfully imaged saved 128 million mesozooplankton size range, 17 which were processed real-time via AI. Data loss occurred along pipeline, mostly due processing limitation Nevertheless, we found similar variability counts classes output dashboard (after loss) post-survey entire dataset. concept offers rapid cost-effective method monitoring trends events at fine temporal spatial scales, thus making most continuous collection time allowing adaptive sampling be deployed. Given pace improvement tools, it anticipated will soon possible deploy expanded classifiers more performant computer processors. use imaging tools still its infancy, industrial scientific applications presented therein being open-ended.

Abstract Marine and coastal ecosystems, such as seagrasses, mangroves, coral reefs, provide a range of essential provisioning, regulating cultural ecosystem services. Recent United Nations guidelines on accounting (SEEA EA) emphasise the need for biophysical data foundation compiling accounts conducting economic evaluations developing indicators informing policies interventions. However, availability marine ecosystems is limited with respect to terrestrial ones. Moreover, collection extent condition required (EA) often not aligned existing habitat monitoring strategies. This study aims address scarcity spatial facilitate integration current strategies scope EA. We propose application design-based inference estimation, mapping, key ecological attributes ecosystems. focus Posidonia oceanica , an endemic seagrass Mediterranean Sea, but proposed strategy adaptable other The benefits appropriate probabilistic sampling schemes assessing P. are explored via simulation testing. performance different sample in artificial populations reveals that reliable estimates density (as well their precision) can be obtained even low sizes. empirical viability our methodology exemplified using collected meadow located Italian Protected Area (Puglia region, Southern Italy).

This study provides a comprehensive evaluation of contamination levels in the Romanian Black Sea within framework Marine Strategy Framework Directive (MSFD). Over course five oceanographic expeditions between 2020 and 2022, data were gathered from 70 stations transitional, coastal, shelf, offshore waters Sea. Analyses conducted on water, sediment, biota samples for key contaminants: heavy metals (HMs), polycyclic aromatic hydrocarbons (PAHs), persistent organic pollutants (POPs) such as organochlorinated pesticides (OCPs) polychlorinated biphenyls (PCBs). The assessment identified hotspots near riverine inputs, urban runoff, harbor activities, industrial discharges. Offshore also showed measurable pollutant levels, likely diffuse sources atmospheric deposition. findings reveal widespread HMs, PAHs, POPs across Sea, with concentrations certain areas exceeding acceptable environmental thresholds, highlighting ongoing challenges regional pollution management. PAHs prevalent both nearshore regions, while OCPs PCBs detected various matrices, significant observed water samples. emphasizes importance integrated assessments MSFD framework, suggesting that future evaluations should complement “one out-all out” (OOAO) approach multi-metric tools, to enhance robustness status reporting. Despite improvements some areas, remains critical challenge, requiring strengthened regulations, improved waste management, increased cooperation mitigate risks marine ecosystems. provide valuable upcoming national cycle (2018–2023) highlight need sustained monitoring coordinated efforts ensure long-term sustainability.

Seagrass meadows are well-known for their capacity to capture and store blue carbon in sediments. However stocks vary significantly between meadows, spanning more than three orders of magnitude on both local global scales. Understanding the drivers seagrass could help improve strategies incorporating into management plans. Here, we measured sediment eelgrass (Zostera marina) unvegetated areas along Norwegian coast, wide gradients temperature, wave exposure, water depth, salinity, biomass. Carbon were generally higher adjacent areas, yet they displayed considerable variation (400 - 30 000 g C m
