They may include aerial video surveys orground-level assessment surveys. The composition and respon-sibility of the survey team will depend on t
18、he responseorganization and objectives. The magnitude and type of datasets collected may likewise vary with the nature of the spill andoperational needs.4.4 Consistent data sets (observations and measurements)on shoreline oiling conditions are essential within any one spillin order to compare the da
19、ta between different sites orobservers, and to compare the data against existing bench-marks or criteria that have been developed to rate the nature orseverity of the oiling. To the extent possible, consistency is alsodesirable between different spills, in order to benefit fromprevious experiences a
20、nd cleanup decisions.4.5 It is recognized that some modifications may be appro-priate based on local or regional geographic conditions or uponthe specific character of the stranded oil.5. General Considerations5.1 Shoreline conditions can be described in terms of thelength, width, depth, distributio
21、n, quantity, and character of oilcontamination. These six different types of data are collectedby direct measurement or direct visual estimates calibratedagainst existing scales or indices. Standard definitions anddescriptors of these data have been developed (Sections 6 and7). Second-order applicat
22、ions of the basic data are further usedto aid response planning (Sections 8 and 9).5.2 Descriptions of shoreline oiling conditions are typicallyreferenced to the lateral (seaward to landward) shorelinezonation. The location of the stranded oil within the intertidalzone affects operational access tim
23、e and oil persistence.5.2.1 Tidal zonation is described in terms of the supra-tidal,upper/mid/lower intertidal, and sub-tidal zones.5.2.2 Non-tidal shoreline zonation is described in terms ofthe supra/upper/lower swash zone for lacustrine (lake) envi-ronments and the over/upper/lower bank or midstre
24、am forriverine (river) environments.5.3 Oil persistence and the choice of cleanup options will bedifferent for subsurface oil as opposed to surface oil. Descrip-tions of shoreline oiling conditions should distinguish betweenthe oiling of surface sediments from that on the subsurfacesediments (vertic
25、al zonation). On coarse sediment beaches, itcan be difficult to differentiate the vertical boundaries. Fig. 1illustrates an approach for discriminating those boundaries.5.4 For beaches with fine sediments (that is, pebble, gran-ule, sand, and mud), the subsurface begins at 5 cm below thesurface. If
26、a pit were to reveal oiling in sand from the surfacedown to 20 cm, the upper 5 cm would be classified as surfaceoil and the remainder as subsurface. However, the oiledinterval would still be shown as 0 to 20 cm.5.5 For beaches with coarse sediments (that is, cobble andboulder), the subsurface begins
27、 at the bottom of the surfacematerial (that is, where the top layer of cobbles or boulderscontact the underlying layer of sediments).5.6 Where asphalt pavement exists on the surface, thesubsurface begins at the bottom of the pavement.5.7 Definitions of the inorganic sediments based on size areas fol
