What is the isobath (water depth) contour interval on the bathymetry map of Cortes Bank in Figure 15? Hint: Note that the labeled isobath contours (the thicker ones with fathom values) are spaced five contour intervals apart from one another. So, the contour interval will be diffrence between those two adjacent thicker, labled isobaths divided by five. For example, if the two adjacent thicker, labled contour values were 1000 and 500 fathoms (with four thin, unlabled isobaths in between), then the contour interval for that map would be (1000-500)/5 = 100 fathoms interval. 30' 20' JOINS CHART 18720 10' 119° 50 185 190 433 545 76 64 175 48 57 205 73 50 43 30 142 728 S/ 327 32 210 670 45 56 41 200 44 200 266 48 380 302 128 190 0y dan 21 39 691 30 420 124 71 46 224 24 70 179 64 C 235 160 52 330 573 40 40 ' 66 46 720 574 60 159 194 -200- 402 125 Y43 Sh d 326 275 150 MS 91 45 54 33) 100 371 111 130 307 E- 117 100 95 95 (210 357 090 127 83 183 Co iky 467 83 41A 61 74 86 81 A 66 111 612 34 141 38 420 663 276 667 530 64 50 36 79 40 42 51 53 50 30 176 316 43 Co Sh 722 49 48) 58 120 239 363 48 37 730 644 rky 38 50 K 120 2478 706 275 314 50 47 41 47 57 71 44 S Sh 47 46 32° 30- 202 -30 53 101 42 745 20 52 342 495 SM (19 B. 31 2 C 29 C 660 357 34 27 47 28 Alshop Rock 14 33 542 39 S Sh s, 6, 275 48 41 48 (25 46 600 611 AR BELL 24 1613 346 81 40 49 35 143 39 ky 04 47 47 67 57 4604 Y 20s PA 810 134 162 184 201 133 00 171 841 30 119° 50 20' 10 Each side bar (black or white) = 1 minute latitude 1 minute latitude = 1 nautical mile Soundings in Fathoms 1 fathom = 6 feet

Transcribed Image Text:What is the isobath (water depth) contour interval on the bathymetry map of Cortes Bank in Figure 15?
Hint: Note
that the labeled isobath contours (the thicker ones with fathom values) are spaced five contour intervals apart from one
another. So, the contour interval will be diffrence between those two adjacent thicker, labled isobaths divided by five.
For example, if the two adjacent thicker, labled contour values were 1000 and 500 fathoms (with four thin, unlabled
isobaths in between), then the contour interval for that map would be (1000-500)/5 = 100 fathoms interval.

1 minute latitude = 1 nautical mile
Soundings in Fathoms
1 fathom = 6 feet
Expert Solution
Step 1
Isobaths are imaginary lines that connect surfaces with equal depth. In the question, a contour map of Cortes bank is being provided. The depth difference between two consecutive isobaths is always the same. It is known as the contour interval.
