Ocean Lab Report Sample

Ocean Lab Report Paper We went to Cortex Madder Salt Marsh, which is located 12 miles North of San Francisco, to examine how rising and falling of tide effect on water level in the marsh and channel. My hypothesis is tide and water level of marsh and channel has positive relationship. The rising tide may raise the water level of marsh and falling tide make water level of marsh decrease. Therefore, since our experiment was limited in few hours, the water level of marsh will be changed (up or down) in few centimeters. The location map M-1) and study area map (M-2) will be attached on next page. Methods To measure and compare the water level of marsh and channel, the class moved along the levy and placed meter sticks into marsh (B) and opposing channel (A). We had four locations for variable: The T (1), Caution Sign (2), Merits Bench (3), and the Point (4). Since the meter sticks were not exactly placed to set O as the begging of change, the 0 was adjusted depend on the location. The experiment location started with 1 to 4 and came back from 4 to 1. Therefore, each location as different elapsed time. For example, site 4 (The Point) has shortest time because we put meter sticks and took off without any moving location. Result Our data has two tables because it contains data from two classes. First data is from Wednesday 19th (T-1), which is our class and the other data is from Thursday class (T-2), 20th of July. The location and the experiment time period are same for both data tables. The Tables are attached on following page. The result of T-1 and T-2 is different. T-1 does not have any significant change in eater level the greatest change was -CM/h at AAA.

On the other hand, only 1 location does not have change in the other groups table. Most of velocities from T-2 are negative. Therefore, the water level is decreasing. No matter the experiment time is almost same (None of data has difference more than 10 minute For example, in T-1, the time in for IA is 14:39 pm and in T-2, the time in for IA is 14:33 pm), the result from each table has large difference. I assume the difference cause by having different tide cycle on both days. Discussion To confirm my assumption, which is each day has different tide cycle, I compare our data to Cortex Madder tide table. On Wednesday 19th, Cortex Madder Creek has first low tide at 3:37 AM and second low tide at 2:57 pm. The first high tide was at 10:05 am and the next high tide was at 9:22 pm. The tidal coefficient was 67 (middle). The maximum high tide recorded in the tide tables for Cortex Madder Creek which is of 7. 2 Ft and a minimum height of -2. 0 Ft. Therefore, during experiment (2:39 pm first in and 4:01 pm last out), we had second low tide after e put meter stick on B but before AAA. Then, the graph shows that the tide started to rise slowly during rest of period. B (2:40 4:01 pm), AAA pm) and B(3:13-3:38 pm) have positive velocity responding to the tide table. On Thursday, 20th of June, the first low tide was at 4:28 am and the next low tide at 3:54 pm. The first high tide was at 11:12 am and the next high tide was at 10:10 pm. The tidal coefficient was 77 (high). The maximum high tide is of 7. 2 Ft and a minimum height of -2. 0 Ft. The fist time in of meter stick was 2:33 pm and the last mime out of meter stick was 3:57 pm on Thursday.
