“…• Benthic landers and crawlers. A range of devices have been developed which remain on the seabed for protracted periods of time some of which photograph the seabed repeatedly (e.g., Lampitt and Burnham, 1983;Lampitt, 1985) or can take time series sediment samples when crawling over the seabed (Purser et al, 2013). These provide unique information about the arrival of debris on the seabed and the interaction with this rather different benthic ecological community.…”

Plastics and other artificial materials pose new risks to the health of the ocean. Anthropogenic debris travels across large distances and is ubiquitous in the water and on shorelines, yet, observations of its sources, composition, pathways, and distributions in the ocean are very sparse and inaccurate. Total amounts of plastics and other man-made debris in the ocean and on the shore, temporal trends in these amounts under exponentially increasing production, as well as degradation processes, vertical fluxes, and time scales are largely unknown. Present ocean circulation models are not able to accurately simulate drift of debris because of its complex hydrodynamics. In this paper we discuss the structure of the future integrated marine debris observing system (IMDOS) that is required to provide long-term monitoring of the state of this anthropogenic pollution and support operational activities to mitigate impacts on the ecosystem and on the safety of maritime activity. The proposed observing system integrates remote sensing and in situ observations. Also, models are used to optimize the design of the system and, in turn, they will be gradually improved using the products of the system. Remote sensing technologies will provide spatially coherent coverage and consistent surveying time series at local to global scale. Optical sensors, including high-resolution imaging, multi-and hyperspectral, fluorescence, and Raman technologies, as well as SAR will be used to measure different types of debris. They will be implemented in a variety of platforms, from hand-held tools to ship-, buoy-, aircraft-, and satellite-based sensors. A network of in situ observations, including reports from volunteers, citizen scientists and ships of opportunity, will be developed to provide data for calibration/validation of remote sensors and to monitor the spread of plastic pollution and other marine debris. IMDOS will interact with other observing systems monitoring physical, chemical, and biological processes in the ocean and on shorelines as well as the state of the ecosystem, maritime activities and safety, drift of sea ice, etc. The synthesized data will support innovative multidisciplinary research and serve a diverse community of users.

“…This is the result of very limited in-situ observations. Deep-sea time-lapse photography has proved valuable in recording the feeding behavior and burrow creation of echiurans (Bett and Rice, 1993;Bett et al, 1995;Ohta, 1984), the foraging behavior of enteropneusts (Jones et al, 2013;Smith et al, 2005) and bathyal shrimp (Lampitt and Burnham, 1983), the activity and bioturbation of echinoderms (Bett et al, 2001;Vardaro et al, 2009), and the behaviour of anthozoans (Ansell and Peck, 2000;Lampitt and Paterson, 1987). Time-lapse imagery has previously been used to observe the movement of I. vagabunda between burrows, leading to the suggestion that it had a hemisessile lifestyle (Riemann-Zürneck, 1997b).…”

a b s t r a c tIosactis vagabunda Riemann-Zürneck, 1997 (Actiniaria, Iosactiidae) is a small endomyarian anemone, recently quantified as the greatest contributor to megafaunal density (48%; 2372 individuals ha À 1 ) on the Porcupine Abyssal Plain (PAP). We used time-lapse photography to observe 18 individuals over a period of approximately 20 months at 8-h intervals, and one individual over 2 weeks at 20-mine intervals, and report observations on its burrowing activity, and both deposit and predatory feeding behaviours. We recorded the apparent subsurface movement of an individual from an abandoned burrow to a new location, and burrow creation there. Raptorial deposit feeding on settled phytodetritus particles was observed, as was predation on a polychaete 6-times the estimated biomass of the anemone. Though essentially unnoticed in prior studies of the PAP, I. vagabunda may be a key component of the benthic community, and may make a critical contribution to the carbon cycling at the PAP longterm time-series study site.

“…A simple, but effective, example of this technique is given by Harvey (1996) in a study of deep-water wood boring bivalves. Wood panels were opportunistically deployed on an SOC Bathysnap system (Lampitt & Burnham, 1983). When the mooring was recovered some 20 months later the wood panels yielded over 400 specimens of a new species of Xylophaga.…”
