Working Map for Bath from 1969. “>X” refers to depths greater than X feet. Lines are transect lines. Green-highlighted numerals are the 28 random sampling points. Orange/yellow highlighted numerals are the 16 “stations”. “M”: Main Transect. “S4A” – 4th transect towards the south from the M transect. Scales at bottom left in yards, meter scale inserted. “Canada began its transition to the metric system (SI) in 1970, with the process largely taking place netween 1975 and 1985. Key milestones included the introduction of Celsius in April 1975, followed by road signs and gasoline sales in the late 1970s, creating a hybrid system still used today” (From Google AI)

A Note on the Distances. Photos were ancillary to the recorded observations on Transect lines and for quadrats at Stations, hence the distances seaward on the Transect Lines given below for particular photos are approximate.*
* Distance were estimated by calculating the meters traversed per minute between two points x, and y that were recorded in photos (hence there is a photo-time) and that were specifically noted in the field data (hence their distances from the beginning of the transect are known), and applying that to estimate the distance for points between x and y; and/or by descriptions in the field data that corresponded to photos.
 Hi-Tech equipment: Pole 2,2 m, marked at 10 cm intervals for measuring distance and depth; depth gauge (for depths > 2.2 m); watch; map. Camera times may differ from watch times, but intervals are the same. |

 2025 – #066 Scarp at approx 148 m. The scarp faces seaward, likely produced by it being in an area if strong outgoing currents on high wave action days |
