 Results of Drift Bottle Experim.ents ^n the Pj^tssamaquoddy Area 



In order to furnish a check on the surface water movements in the 

 Passamaquoddy ^re^ , drift bottle experiments were cpirried out in the 

 Spring of 1930. ^in ordinary type of catsup bottle with a metal drag 

 attached, ond contf>Lning a post card, was used in the experiments « A 

 piece of red cloth was placed in the neck of the bottle ^^nd sealed 

 with a waxed cork. The bottles were put out nccording to a definite 

 plan, and the plotted returns used to furnish a picture of the sur- 

 face circul'^tion of the region. The lines along which these bottles 

 v?ere placed, *n groups of four ot one mile intervals, nre illustrated 

 in figures 30, 31, 32, 33 and 34, The times nt which the bottles 

 were released and the time at v^hich they were found is used to 

 determine the maximum time of drift. Those bottles returned v^ithin 

 the shortest period of time were used to determine the most probable 

 direction ^nd rate of drift. These form the basis upon vi'hich the 

 various drifts were plotted. Mavor's (1922) results are also used 

 as a basis for plotting the resultant movements. It is to be borne 

 in mind that drift bottles are carried to and fro by the tides, and 

 thnt the resultant movement or circulation over a period of time is 

 represented by the paths of the various bottles. The results of the 

 returns from the various drift bottle lines will be dealt with by 

 dividing the investigation into five series A, B, C, D, and Eo
