SBC LTER: Reef: Kelp Forest Community Dynamics: Fish abundance (Reformatted to the ecocomDP Design Pattern)|生态学数据集|鱼类种群动态数据集

This data package is formatted as an ecocomDP (Ecological Community
Data Pattern). For more information on ecocomDP see
https://github.com/EDIorg/ecocomDP. This Level 1 data package was
derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-sbc/17/35. The
abstract below was extracted from the Level 0 data package and is
included for context: These data describe the abundance and size of fish species as part
of SBCLTER's kelp forest monitoring program to track long-term
patterns in species abundance and diversity. This study began in
2000 in the Santa Barbara Channel, California, USA. The abundance
and size of all taxa of resident kelp forest fish encountered along
permanent transects are recorded at nine reef sites located along
the mainland coast of the Santa Barbara Channel and at two sites on
the north side of Santa Cruz Island. These sites reflect several
oceanographic regimes in the channel and vary in distance from
sources of terrestrial runoff. In these surveys, fish were counted
in either a 40x2m benthic quadrat, or in the water parcel 0-2m off
the bottom over the same area. The two tables in this data package include: 1) The annual benthic
fish community survey which was conducted on 11 reefs once a year
around late July or early August; and 2) The monthly fish survey
which was conducted once a month at a subset of the sites (3 of the
annual sites) The time period of data collection for the annual benthic fish
community survey varied among the 11 kelp forest sites. Sampling at
BULL, CARP, and NAPL began in 2000, sampling at the other 6 mainland
sites (AHND, AQUE, IVEE, GOLB, ABUR, MOHK) began in 2001 (transects
3, 5, 6, 7, 8 at IVEE were added in 2011). Data collection at the
two Santa Cruz Island sites (SCTW and SCDI) began in 2004. The
monthly fish survey at ABUR (Transect 1, 2, and 3), AQUE
(Transect1), and MOHK (Transect 1) in 2002. The Transect 2 and 3 at
ABUR were discontinued in June 2006. See Methods for more information.   The primary research objective of the Santa Barbara Coastal LTER is to investigate
the importance of land and ocean processes in structuring giant kelp
(Macrocystis pyrifera ) forest ecosystems. As in many temperate
regions, the shallow rocky reefs in the Santa Barbara Channel, California, are dominated
by giant kelp forests. Because of their close proximity to shore, kelp forests are
influenced by physical and biological processes occurring on land as well as in the open
ocean. SBC LTER research focuses on measuring and modeling the patterns, transport, and
processing of material constituents (e.g., nutrients, carbon, sediment, organisms, and
pollutants) from terrestrial watersheds and the coastal ocean to these reefs.
Specifically, we are examining the effects of these material inputs on the primary
production of kelp, and the population dynamics, community structure, and trophic
interactions of kelp forest ecosystems.
