The data represent hourly temperatures recorded at four permanent subtidal monitoring sites around San Nicolas Island, CA between November 2015 and October 2019. The temperatures were recorded by TidbiT (registered trademark) v2 model UTBI-001 (Onset Computer Corporation, Bourne, Massachusetts) archival temperature loggers attached at the sea floor. The loggers were deployed approximately 10-12 m deep at Nav Fac (12 m) on the north side of the island, at West End Urchin (11 m) on the southwest side, at east Dutch Harbor (11 m) on the south side, and at Daytona Beach (10 m) near the east end of the island.

This dataset is a compilation of Longfin Smelt observations from multiple sources, including research institutions and museums, and local, state, and federal fisheries agencies.

Data included are DNA sequences used to identify species boundaries among Ichthyophonus-like parasites. Sequences were generated for three gene regions from each parasite isolate. DNA sequences can be downloaded from GenBank (https://www.ncbi.nlm.nih.gov/) as text or fasta files. Accession numbers for each sequence are included in the data table (.csv file). Data includes 87 sequences (99,383 total nucleotides). Once manuscript is accepted there are no restrictions on dissemination of these data.

Four data sets are included here to aid in assessing the influence of substrate complexity on kelp forest ecosystem stability. One data set consists of counts of a suite of kelps and benthic invertebrates on permanent band transects (swaths) at six long-term monitoring sites from 1980-2018. A second data set consists of total counts of adult California sheephead (Semicossyphus pulcher), an important sea urchin predator, on these sites from 1981-2018. The third data set gives an index of the relative substrate rugosity in the form of replicate distances along the bottom profile of each permanent swath. Finally, bottom temperatures recorded from 2015-2019 show the relatively homogenous water mass that encompasses...

The data represent counts of individuals of a suite of kelp and macroinvertebrate species on fixed 10-meter by 2-meter benthic transects on permanent subtidal monitoring sites around San Nicolas Island between 1980 and 2018. There were six sites, each of which had five 20 square meter band transects. The sites were usually monitored twice per year, most often in October and April. The species list is as follows: Stephanocystis osmundacea (formerly Cystoseira osmundacea), Laminaria spp., Eisenia arborea, Pterygophora californica, Macrocystis pyrifera greater than 1 m tall, Macrocystis pyrifera less than 1 m tall, Juvenile Laminariales (genus uncertain), Mesocentrotus franciscanus (formerly Strongylocentrotus franciscanus),...
