 USERS GUIDE FOR DATA INPUT SHEET B 



The following is a description of the data input catagories 

 for the historical coral data. Verbal information Is recorded 

 in numerical code form as for Data Sheet A. All numerical codes 

 are listed in Code Table B. 



Note: This information must be recorded for each photograph 

 examined. All input is right rectified in the spaces provided 

 unless otherwise noted. Abundance data should be recorded using 

 a red pen to allow easy reading of the data sheet. 



1. Dive number: Same as for data sheet A. 



2. Photo number: This is a sequential number of the slide or 

 photograph starting with 001 for the first photograph of the dive. 

 Three digits are allowed for this identification. 



3. Depth: Depth in meters at the site of the photograph. If 

 only one depth value is recorded in the dive record use this value, 



4. Area: The area of the bottom represented in the photograph - 

 or the area which has been counted. This is recorded in meters 

 squared with respect to the Canadian Grid. If the Canadian Grid 

 is not applicable (i.e. on a steep slope or outcrop) approximate 

 the area being counted. Two digits are allowed for this value. 



5. Substrate: This represents the general character of the 

 substrate. Substrate types are codified on the attached Code 

 Table B. Two digits are allowed for this catagory. 



6. Comments A and B: These are general comments about the 

 substrate, biota, etc. Two comments catagories are allowed 

 here (Comments A and Comments B) for flexibility. (i.e. if both 

 ripple marks and biotic associations are noted in one photograph 

 they may both be recorded) . This verbal information is codified 

 In Code Table B with two digits for each comment. This single 

 code listing is used for both Comments A and Comments B catagories 



7. Same: This catagory is checked if the photograph is the same 

 as previous photographs. In such cases, only the dive number 

 and slide number need be recorded. This check will automatically 

 tell the keypuncher to duplicate the previous data card. 



8. Taxa: The most commonly found taxa are listed on the data 

 sheet. Each taxon is assigned a three digit code number. 



Two digits are allowed next to each code number for abundance 

 data. If no specimens of a particular taxon are found no record 

 need be made. Open spaces are available on the right hand side 

 of the data sheet for rarer taxa. These are listed with their 

 assigned code number in Code Table B. Only those taxa which are 

 present in a photograph need be recorded or listed. If taxa 

 are found which are not listed in the code table, they may be 

 added to the listing and given a three digit code number. These 

 code numbers should be unique and sequential in order to avoid 

 confusion.
