Abstract

These data are from Onset HOBO U22 data loggers recording at 1-minute intervals deployed at various depths on instrument moorings from June to August in 2018 and 2019. Moorings were located inside and outside of a kelp forests near the Monterey Peninsula, California, USA.

Sampling Locations:
Sampling was conducted near the Monterey Peninsula near Pacific Grove and Monterey, California, USA. Kelp sites ranged from 8.8 to 10.3 meters deep and offshore sites ranged from 13.1 to 16.5 m deep.

Instrument moorings were deployed in 2018 in the following areas: a wave-protected kelp forest, ~100 meters offshore of the protected site, in a wave-exposed site devoid of kelp (historically has had kelp), and ~100 meters offshore of the exposed site.

Instrument moorings were deployed in 2019 in the following areas: a wave-protected kelp forest, ~175 meters offshore of the protected site, in a wave-exposed kelp site, and ~180 meters offshore of the exposed site.

Location Abbreviations:
PK = Protected kelp 2018,
PO = Protected offshore 2018,
EK = Exposed ‘kelp’ 2018,
EO = Exposed offshore 2018,
MK = Protected kelp 2019,
MO = Protected offshore 2019,
OK = exposed kelp 2019,
OO = Exposed offshore 2019.

Methodology:
In 2018, HOBO U22 temperature loggers were deployed at PK at 6.5 and 7.3 meters above the bottom, at PO at 15.5 and 17 meters above the bottom, at EK at 9.5 and 10.7 meters above the bottom, and at EO at 12.75 and 13.7 meters above the bottom. In 2019, instruments were deployed at MK at 8 meters above the bottom, at MO at 15 meters above the bottom, at OK at 9.5 meters above the bottom, and at OO at 14 meters above the bottom.

Instruments had to be swapped out periodically during deployment due to data storage capacity. Time and depth of deployment were recorded each time a sensor deployed.
