Temperature data from 4 depths at the study site in the giant kelp forest habitat of the Central California Coast. Temperature was recorded every 5 minutes from June 2010 to October 2012.
Onset Stowaway Tidbits (+/- 0.2C) were positioned at 0.5, 4.8, 8, and 13.5 m along a mooring line at the study site. The loggers were set to record temperature every 5 minutes and were swapped out approximately every 3 months by divers.

Data were downloaded in the lab and converted to tab delimited text files. Data were quality controlled and trimmed to fit accurate temperature recordings and cut to minimize the data gaps between collection and deployment of new loggers. After deployment the loggers took approximately 2 hours to equilibrate to ambient water temperature. Comparison between the temperature data on a logger just prior to collection and the temperature data at the time of deployment for a logger collected the following month were used to identify accurate data measurements and outliers were removed from the data set. Occasionally an entire record for a particular depth was lost due to instrument failure.
Files were named labeled with a letter indicating which depth in the water column they were collected (S=surface (0.5 m), T=top (4.8 m), M=Middle (8 m), B=bottom (13.5 m)). Dates in the file names indicate the dates of deployment to retrieving the tidbits.
Missing Dates:
Surface - June 2010 to September 2010
Top - July 2012 to September 2012
Mid - September 2011 to December 2011

NSF Award Abstract:
Kelps inhabit a narrow band of the Earth's ocean margins, yet they sustain some of the most diverse and productive ecosystems on the planet. Despite over 50 years of intensive field and laboratory research, however, much remains to be understood about the processes that determine the dynamics of kelp populations, and the subsequent consequences for the diversity and productivity of their associated communities. This limitation is due largely to the fact that processes regulating kelp system productivity, dynamics, and diversity are determined by how different kelp species interact with environmental variability over ecological and evolutionary timescales. In the face of imminent ocean climate change, how will individual kelp taxa respond to rising ocean temperatures or decreasing nutrients? This project will use a combination of laboratory and field studies to understand interactive effects of changing temperature and nutrients on gametogenesis, fertilization, and sporophyte recruitment of kelp. This project will use 9 kelp taxa from California, British Columbia, Australia, Mexico, South Africa, and Chile to test for local adaptation vs. phylogenetic patterns in these traits and to understand whether the level of stress experienced by a population determines regional tolerance patterns. The project will integrate research activities into a novel curriculum at Moss Landing Marine Laboratory and will involve students in laboratory and field studies. These activities will help students to develop good laboratory skills and facilitate the development of critical-thinking as it pertains to the comparative analysis of kelp life histories, conceptual models of life history evolution, and ecological implications of climate change.
