“…Some real-time monitoring and responsive action has also been undertaken in the benthic environment. In Norway, Statoil has monitored the potential impacts on a coral reef system at the Morvin oil field, which included sediment sampling, video observations, sensors and sediment traps (Tenningen et al, 2010;Godø et al, 2014). The sensor data were available in real time and enabled drillers to observe if selected reef sites were being impacted by drilling activities.…”

“…In the context of the petroleum industry, which has a well-known pollutant potential, oily sludge represents a serious environmental problem. [1][2][3] The oily sludge is a stable W/O (water in oil) emulsion of water, solids and petroleum hydrocarbons generated in the petroleum refining process during the dissolved air flotation process. 2 According to the literature, 4 it is constituted by water (90-99 wt.%), crude oil waste (0.5-3 wt.%) and mineral particles (0.2-7 wt.%).…”

This work reports the remediation of a liquid residue derived from the thermal treatment of petrochemical residues by advanced oxidation processes. Firstly, degradation studies of phenol aqueous solutions by heterogeneous photocatalysis, Fenton, and photo-Fenton were conducted. Fenton processes showed a higher efficiency, mainly in the UVA photo-assisted mode (94% in 3 min), and henceforward it was chosen for the remediation of the residue. However, the high organic load of the raw residue (6,000 mg L-1 of chemical oxygen demand (COD)) limited the efficiency of the Fenton processes. Hence, the raw liquid residue was diluted with the scrubber residue, produced during the thermal treatment of the petrochemical residues, reducing the COD to values close to 2,000 mg L-1. The photo-Fenton treatment allowed the removal of approximately 95% of the COD load, decreasing the residual concentration of phenolic compounds from 213 to 0.5 mg L-1. At the same time, the concentration of BTEXs (benzene, toluene, ethylbenzene and xylene) were reduced to values lower than the limit of quantification (LOQ) of the chromatographic technique. Therefore, the photo-Fenton process is an efficient alternative to the remediation of residues with high complexity and with high COD values, like the ones obtained in the petrochemical industry.

“…This has encompassed investigations of relationships between different species (Riedel et al 2008), their movements (Kaufmann & Smith 1997), growth patterns (Barnes & Crossland 1980) and their influence on the environment (Rowe et al 1974). Physical (http://www.bbc.co.uk/nature/16250444) and anthropogenic (Davis et al 2012;Godø et al 2014) processes that may affect biological life have also been visualised with unattended time-lapse camera systems deployed by divers. A recent, and impressive application of this method took place in Antarctica (http://www.bbc.co.uk/nature/16250444) at Little Razorback Island where a BBC crew filmed for the first time the formation of a brinicle -a fragile tube of ice that forms around the sinking plume of cold, dense water extruded from the sea ice (Cartwright et al 2013).…”

Photographic time-lapse techniques are especially useful in the marine realm for visualising long-term processes and remote monitoring of sites/objects/organisms where the presence of researchers might cause some study bias, or access is limited or impossible. With rapid advances in technology development there is easy access to new tools for time-lapse photography and setting up systems is relatively inexpensive. The essential requirements for low-cost autonomous timelapse camera systems to be self-sufficient and reliable enough to withstand the extended periods of deployment (up to one year) on the sea floor at up to 50 m depth are presented. In this example a custom-made system developed originally for monitoring the activity of filter/suspension feeders and scavenging fauna in the polar conditions is described. The major issues encountered during the preparation and deployment which should be of benefit to users involved in underwater time-lapse photography are considered.
