Corte Madera Scientific Report
Abstract
I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result, I learn that the water level and tide have positive relationship. However, when tide changes its direction, the water level is likely to stay or little change.
Introduction
On June 19th, my classmates and I had field trip for Oceanography Lab (OCN 101) class with Professor Ocean Matt Horrigan. We went to Corte Madera 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), Meris’ Bench (3), and the Point (4). Since the meter sticks were not exactly placed to set ‘0’ 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 has 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
