General Information

Title:SBCLTER: Transect Depths for Long Term Kelp Removal Experment
Short Name:Transects: Benthic LTE KR sites
Identifier:knb-lter-sbc.44
Abstract:
These data summarize depth information (mean, standard deviation and coefficient of variation) for all of the transects surveyed as part of the SBC LTER Long Term Kelp Removal Experiment. All data are expressed in meters, referenced to mean lower low water (MLLW). Each value is the result of 160 observations, four at each meter (n=160). The sampling locations in this dataset are 40 meter transects at four reef sites along the mainland coast of the Santa Barbara Channel, California, USA. These data were recorded in 2010.

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:  
Description:

Depth Surveys

A diver reels out a 40 meter tape along the marked transect location. Using a dive computer, the diver records depth readings at points 0.25 and 0.75 meters offshore and 0.25 and 0.75 meters inshore for every meter along the transect. There are a total of 160 measurements for each 40 meter transect.

Instrument(s): Suunto Gecko/Viper Dive Computer (set in meters)
Instrument(s): Meter tape
