6、Significance and Use3.1 Systematic surveys provide data on shoreline characterand oiling conditions from which informed planning andoperational decisions may be developed with respect to shore-line cleanup (1-3).33.2 Surveys may include one or more of three components,listed below. The scale of the

7、affected area and the availabilityof pre-spill information will influence the selection of surveycomponents and the level of detail.3.3 The aerial reconnaissance survey provides a perspectiveon the overall extent and general nature of the shoreline oilingconditions. This information is used in conju

8、nction withenvironmental, resource, and cultural sensitivity data to guideshoreline protection, recovery of mobile oil, and to facilitatethe more detailed response planning and priorities of theresponse operations.3.4 The aerial video survey(s) provide systematic audio andvideo documentation of the

9、extent and type of shoreline oilingconditions, physical shoreline character, and potential accessrestrictions.3.5 The ground assessment survey(s) provide the necessaryinformation and data to develop appropriate shoreline responserecommendations. A field team(s) collects detailed informationon shorel

10、ine oil conditions, the physical and ecological char-acter of oiled shorelines, and resources or cultural features thatmay affect or be affected by the timing or implementation ofresponse activities.3.6 In order to ensure data consistency it is important to usestandardized terminology and definition

11、s in describing oilingconditions, as provided in Guide F1687.4. General Considerations4.1 The specific survey procedures and the magnitude of thedata sets collected will vary with the scale of the spill (thelength and distribution of oiled shoreline and quantity of oil),the nature or complexity of t

12、he shoreline, and the needs of theresponse organization (1).4.2 Following a spill in which only a few kilometers ofcoast have been oiled, one ground survey team may be able toaccomplish all of the goals in an appropriate time frame.4.3 As the scale of the affected area increases, it may benecessary

13、to conduct an aerial video survey that is followed bya ground assessment using one or more teams.4.4 Following spills that affect long sections of coast (forexample, more than 100 km), the sequence of an initial aerialreconnaissance, an aerial video survey and ground assessment1This guide is under t

17、e stages requires a separate surveydesign, the assignment of duties to personnel, logistics plan-ning, and the establishment of survey and documentationprocedures.4.6 All surveys are conducted during the lowest one-quarterto one-third of the tidal cycle to ensure maximum (viewing)exposure of the int

18、ertidal zone.5. Segmentation5.1 The coast is divided into working units called segments,within which the shoreline character is relatively homogeneousin terms of physical features and sediment type.5.2 Each segment is assigned a unique location identifier(for example, an alpha-numeric code).5.3 Segm

19、ent boundaries can be either prominent geologicalfeatures (headlands, streams, etc.), changes in shore/substratetypes, or, more importantly, alongshore changes in oil condi-tions.5.4 Segment lengths are short enough to obtain adequateresolution and detail on the distribution of the oil for planninga

20、nd operational decisions. Most segments of oiled shorelineswould be in the range of 0.2 to 2.0 km.5.5 If segments already exist as part of a pre-spill planningexercise or sensitivity mapping database, segment boundariesmay need to be adapted, segments subdivided, or the segmentcodes revised, or some

21、 combination thereof, to reflect theoiling conditions created by a spill.6. Aerial Reconnaissance Survey(s)6.1 An initial aerial survey(s) is conducted along coastlineswithin the spill path. The objective is to determine whichshorelines have been oiled, in order to provide an overallperspective and

22、scale with which to plan for a more systematicdocumentation or assessment survey.6.2 This survey can be augmented with information from ahigh-altitude surveillance and tracking program. In some casesthis survey can be combined with other aerial reconnaissanceactivities being conducted to locate and

23、visually observe oil onwater (Practice ).6.3 Fixed-wing or rotary-wing aircraft fly the coast atslow-speed flight at altitudes in the range of 75 to 150 m.Helicopters are preferred over fixed-wing aircraft, as theypermit landings to confirm observations made from the air.Among fixed-wing aircraft, t

24、hose with the wing mountedabove the fuselage (high-wing aircraft) are essential to allowthe required visibility of shoreline features.6.4 If possible, the survey team will consist of an oilobserver and navigator/recorder. The observer should be anoil-spill specialist familiar with oil on shorelines

25、and able todistinguish between natural materials (stranded kelp, blacklichen, heavy mineral bands, etc.) and oil. The navigator logsthe flight lines, locates a section of shoreline on maps or charts,and records oil observations.6.5 Records of observations may be made on maps andnotebooks. Video and

26、still photography can also be used to adda visual record of examples of the oiling conditions andshoreline character for immediate use by planners and decisionmakers.6.6 An aerial reconnaissance is generally not required wherethe presence of oil on the shore has been defined clearly fromother source

27、s or where the affected coastline is short enough inlength that an aerial video survey can be completed during onelow-tide cycle.7. Aerial Video and Mapping Survey(s)7.1 The aerial video recording and mapping survey(s) areconducted on coasts where there is known or expected oiling.The survey is used

28、 to provide detailed and systematic docu-mentation on the extent and type of shoreline oiling and othershoreline conditions.7.2 Small high-wing or rotary-wing aircraft fly the coast atvery slow speeds at altitudes in the range of 25 to 75 m.7.3 The primary survey team consists of an oil observer and

29、a navigator. The navigator records and maps relevant flightinformation. The oil observer operates the video camera andprovides a continuous audio commentary, for which the colorvideo image provides a visual image frame of reference. Insome cases a video technician may be desirable for theoperation a

30、nd quality control of the audio and video record-ings.7.4 The oil observer/videographer is an oil-spill specialist,who can identify the shoreline substrate and form and distin-guish between natural shoreline materials and stranded oil.Duties of the oil observer are as follows:7.4.1 To identify or cr

31、eate segment boundaries and describetheir location on one of the audio channels. These are alsorecorded on a set of flight-line maps or charts by the navigator.7.4.2 To video the shore zone through an open door orwindow continuously, with the camera angled down (30 to 45)and slightly ahead of the ai

32、rcraft (15 to 30) so that the areabeing described comes into focus and the foreground duringthe commentary. Video resolution is best when the sun isbehind the aircraft.7.4.3 To provide a continuous descriptive commentary onthe shoreline oiling conditions, including the (1) length andwidth of the oil

33、ed areas and the oil distribution (percent surfaceoil cover), (2) physical shore-zone character, and (3) otherpertinent features such as access locations or constraints.7.5 Video recording equipment requires either a camera/recorder/color monitor system or a camrecorder system. Bothmust have on-scre

34、en date/time, audio recording, and lowlightrecording capabilities. Other requirements include an indepen-dent, stabilized power supply or converter and a voice-activated two-channel audio recording and communicationssystem between all crew members, including the pilot. Alsodesirable is the capabilit

35、y for location (geographical position-ing system) overprint on the image, a stabilized camera mount,and small inboard color monitor(s).8. Ground Assessment Survey(s)8.1 Shoreline ground assessment surveys are conducted onoiled and unoiled segments within the affected area that mayF1686 092have been

36、identified to provide detailed, systematic observa-tions that are used to guide the development of appropriateresponse priorities, endpoints, constraints, and treatment tactics(4 and 5).8.2 The scale of the ground survey is dependent on the sizeand character of the area affected and the intended use

37、 of thesurvey data.8.3 Where more than one survey team is used, appropriatemeasures must be taken to ensure consistency in proceduresand terminology.8.4 Typically, a ground survey team must contain an oilspillshoreline specialist and may include a coastal ecologist,cultural resources specialist, and

38、 different agency representa-tives, depending on available personnel and the complexity ofthe spill.8.4.1 In the most simple form, the survey is conducted by anoil-spill shoreline specialist who has a basic understanding ofmarine coastal geomorphology and processes, oil behavior, andcleanup. Using s

39、tandardized terms, definitions, and procedures,this person documents the oiling conditions and the physicalcharacter of each oiled segment.8.4.2 A specialist in coastal ecology may be included in theteam(s), as necessary, to identify and assess intertidal commu-nities and evaluate the effect of the

40、oil or the potential effect oftreatment options. The ecologist may also (1) verify theoccurrence of sensitive habitats or species (in the segment) thatwere identified previously in sensitivity maps or databases, (2)identify and document human use activities in a segment, and(3) identify procedures o

41、r constraints on response operations tominimize effects on the biota.8.4.3 A cultural resources or archaeological specialist maybe included on the team(s), as necessary, to identify known orsuspected archaeological, historical, or other cultural sites. Thespecialist may also (1) help evaluate potent

42、ial effects or varioustreatment options, (2) if authorized, collect artifacts for theirpreservation, and (3) identify procedures or constraints onresponse operations to avoid potential impacts on the sites in oradjacent to oiled segment(s).8.4.4 Representatives of government agencies, land ownersor

43、managers, the potential responsible party, and the operationsteam may participate as observers to assist in the subsequentdevelopment of response options and constraints.8.5 In its basic form, the survey would document and assessthe surface and, where applicable, subsurface oiling conditions.On shor

44、es where the materials are mobile or where the oil canpermeate into the substrate, it is necessary to dig pits ortrenches to locate and describe oil that has been buried or haspenetrated. The inclusion of ecological or archaeologicalobservations would depend on the purpose of the survey.8.6 Standard

45、 forms are recommended in order to ensure thatall necessary data are recorded or considered in a consistentmanner. These are typically designed to suit the spill situation.An example of a generic shoreline oiling summary (SOS) formis provided in Fig. 1. Simpler forms may be used whereappropriate to

46、the intended purpose of the spill survey. Similarforms may be adapted for use in freshwater or riverineenvironments or on a regional basis to be applicable tonon-temperate or tropical shore-zone conditions.8.7 A field sketch (Fig. 2) is recommended to locate oiledzones within a segment, where the oi

47、l is not distributeduniformly, or to identify shore-zone features. A map sketchrather than a perspective drawing is interpreted more easily andcan include oiling, substrate character, photographic, and scaleinformation.8.8 Still-color photographs or video recordings can supple-ment the completed for

48、m and sketch. More information can berecorded on the audio channel of a videorecorder than can berecorded in a field note book, by sketches or photographs. Thesystem has the advantage over notes or a tape recorder as avisual image is provided of the location under discussion. Thistechnique is partic

49、ularly recommended for surveys or segmentsin which the shoreline or oiling conditions are particularlycomplex, unusual, or spatially variable.8.9 There are several post-survey activities that are optional.Prior to departing a survey site, a team may review individualassessments quickly and discuss findings to ensure that nothingsignificant has been overlooked. At the completion of each dayit is typical to review, recopy, and finish, as necessary, allforms, maps, notes, etc. Completed survey documentationshould be filed or archived as appropriate. Survey findings maybe put on a dat
