“…Cánovas-Molina et al ., 2016, Meyer et al ., 2020). In the past, the use of ROVs has generally been constrained by cost to broad-scale and meso-scale surveys (Bo et al ., 2014; Cánovas-Molina et al ., 2016), however there is now an increasing use of mini-ROVs for smaller scale surveying which would be possible within ports (Buscher et al ., 2020). Whilst video methods are likely to miss detail when it comes to identifying cryptic species, identifying organisms to species level and providing a detailed insight into community structure, the speed with which data can be collected means this method could prove effective in screening for visually distinctive NNS within ports.…”

Ports have long been considered ‘high-risk’ areas for the introduction of non-native species (NNS) and should therefore be a focus of NNS monitoring. The industrial nature of active ports can, however, provide various problems when attempting to carry out monitoring programmes. Current methodologies designed to identify NNS and to describe fouling communities have not been developed specifically for use in active ports and can encounter a number of issues when used in these environments. Here, two surveys were developed and trialled within an active port in South Wales, UK, designed to describe fouling communities, identify NNS and overcome some of the major limitations to conducting surveys within ports. Over a 6-month period, fouling communities dominated by solitary ascidians developed in each survey. Seven NNS were identified, mostly species already recorded in the 1950s, including the Mediterranean crab Brachynotus sexdentatus, and the more recently introduced Japanese skeleton shrimp Caprella mutica. Each survey was evaluated independently with respect to key factors, including the ability to detect NNS and practical aspects of using these survey methods in an applied context. We conclude that whilst each survey can function independently, the use of both survey types in conjunction offers the most robust solution to identifying NNS and describing wider fouling communities within active ports. This research has implications for the future monitoring and management of NNS within UK ports.

“…Within the last twenty years, due to the developments in various different fields like microcontrollers or 3D printing, small observational ROVs have become affordable and available to the public [32]. Due to the low price, the easier set up, and their availability, small ROVs have recently been used in various fields of research, including fish length estimation [33], ecological surveys [32], photogrammetric surveys [34], or water quality surveys [35].…”

Submarine groundwater discharge (SGD) is an important pathway of nutrients into coastal areas. During the last decades, interest of researchers in SGDs has grown continuously. However, methods applied for SGD research usually focus on the aquifer or on the mixing processes on larger scales. The distribution of discharged water within the water column is not well investigated. Small remotely operated vehicles (ROV) equipped with environmental sensors can be used to investigate the spatial distribution of environmental parameters in the water column. Herein, a low-cost multi-sensor platform designed to investigate the spatial distribution of water quality properties is presented. The platform is based on an off-the-shelf underwater vehicle carrying various environmental sensors and a short-baseline localisation system. This contribution presents the results of SGD investigations in the area of Woodman Point (Western Australia). Various potential SGD plumes were detected using a skiff equipped with a recreational echo sounder. It was demonstrated that this inexpensive equipment could be used to detect and investigate SGDs in coastal areas. In addition, the low-cost multi-sensor platform was deployed to investigate the spatial distribution of environmental parameters including temperature (T), electric conductivity (EC), dissolved oxygen (DO), oxidation-reduction potential (ORP), pH, and dissolved organic matter fluorescence (FDOM). Three ROV surveys were conducted from different skiff locations. Analyses of the spatial distribution of the environmental parameters allowed the identification of nine potential SGD plumes. At the same locations, plumes were identified during the sonar surveys. In addition, fuzzy logic was used for the fusion of salinity, DO, and FDOM readings in order to enhance SGD detection capability of the designed multi-sensor system. The fuzzy logic approach identified 293 data points as potential within a SGD plume. Average minimum-distance between these points and the identified SGD plumes was 0.5 m and 0.42 m smaller than the minimum-distance average of the remaining data points of survey one and three respectively. It was shown that low-cost ROVs, equipped with environmental sensors, could be an important tool for the investigation of the spatio-temporal behaviour of SGD sites. This method allows continuous mapping of environmental parameters with a high spatial and temporal resolution. However, to obtain deeper insights into the influence of SGDs on the nearshore areas, this method should be combined with other well-established methods for SGD investigation, such as pore water sampling, remote sensing, or groundwater monitoring.

Methods for accounting of herring spawning grounds area using consumer grade underwater robots and UAVs were worked out. Such devices are promising for use due to their relatively low cost, ease of deployment and application. Experimental procedures were carried out from May 11 to June 9 in the Kruglaya and Tungusskaya bays (the northern part of the Okhotsk Sea) during the period of herring spawning. With the help of underwater robots, spawning grounds should be surveyed by short point diving and short transects. Series of screenshots of bottom, recorded on a mobile device, could be georeferenced automatically. The work should be accompanied by the recording of tracks, station coordinates and other attribute data in a mobile geographic information system (GIS). Unmanned flights over spawning grounds must be carried out in the mode of automatic linear and polygon missions or manually. For the orthophotos production, the optimal height is 150 m with a forward overlap of images no less than 80% and a side overlap no less than 50% (no less than 20% in case of very good bottom visibility and survey conditions). During harsh survey conditions, zigzag flights over spawning grounds at a height of 50 m are preferred with shooting a series of photographs without intersection and no orthophotos production. The materials of underwater and unmanned surveys, integrated into the desktop GIS, provide high accuracy and efficiency in estimating the area of spawning grounds, the maximum degree of documentation and verifiability of the obtained materials.
