Minerals Management Service (MMS) Phase I : study of benthic communities in the Santa Maria Basin and Western Santa Barbara Channel

These specimens come from the Minerals Management Service (MMS) “Phase I” study of benthic communities in the Santa Maria Basin and Western Santa Barbara Channel in 1983–1986. A total of 102 soft-substrate stations and 23 hard bottom stations were surveyed. Further information below is quoted from: Blake, J.A. (1993) 1. Introduction to the Taxonomic Atlas.

The U.S. Department of the Interior, Minerals Management Service (MMS) is endowed with authority pursuant to the Outer Continental Shelf (OCS) Lands Act, the Submerged Lands Act, and the OCS Lands Act Amendments to develop oil and gas resources on the outer continental shelf while providing for the protection of the marine and coastal environment. As part of this responsibility, MMS has sponsored numerous studies through the Environmental Studies Program to develop sufficient baseline information for the evaluation of potential environmental impacts resulting from OCS development. Among the major MMS-sponsored investigations of the benthic communities in the Southern California OCS Planning Area are the 1975-1978 Southern California Bight Baseline Program, the 1983-1986 Assessment of Long-Term Changes in Biological Communities in the Santa Maria Basin and Western Santa Barbara Channel (Phase I), the 1987-1989 Biological Reconnaissance of Selected Benthic Habitats within Three California OCS Planning Areas (a.k.a. CARP, California Area Reconnaissance Program), and the 1968-1991 California Phase II Monitoring Program (CAMP). The hard-bottom monitoring phase of CAMP has been continued as part of Phase III (1991-1995).
Note: Sample labels from the Soft-substrate stations have several identification codes which include a station number, sample type, replicate number, and analysis type. These are as follow: 001 to 200 the range of station numbers; BSS - Benthic Sediment Single (i.e., a non-replicated station); BSR Benthic Sediment Replicate (three replicates taken at this station); BSV Benthic Sediment Variance (subsamples); 01-09 replicate numbers: TX a taxonomy sample. Sample labels having the designation BRA, represents a sample from rocks taken as part of the hard bottom survey.

这些标本来源于1983—1986年美国矿产管理局（Minerals Management Service, MMS）针对圣玛丽亚盆地与圣巴巴拉海峡西部底栖生物群落开展的"第一阶段"研究。本次调查共覆盖102个软基质站位与23个硬质底质站位。下文补充信息引自Blake, J.A.（1993）的《分类学图谱导论》，收录于Blake, J.A.与A. Lissner编纂的《圣玛丽亚盆地及圣巴巴拉海峡西部底栖动物分类学图谱 第一卷：导论、底栖生态学、海洋学、扁形动物门（Platyhelminthes）与纽形动物门（Nemertea）》，加州圣巴巴拉自然历史博物馆出版。

美国内政部矿产管理局（MMS）依据《外大陆架（Outer Continental Shelf, OCS）土地法》《水下土地法》及《外大陆架土地法修正案》，获得在外大陆架开发油气资源的法定权限，同时兼顾海洋与海岸环境的保护。作为该项职责的组成部分，MMS通过环境研究计划资助了多项研究，以积累充足的基线信息，用于评估外大陆架开发可能引发的潜在环境影响。在南加州外大陆架规划区底栖生物群落相关的MMS资助重要调查中，包含1975—1978年南加州湾基线计划、1983—1986年圣玛丽亚盆地与圣巴巴拉海峡西部生物群落长期变化评估（第一阶段）、1987—1989年三个加州外大陆架规划区内选定底栖生境的生物勘察（又称CARP，加州区域勘察计划），以及1968—1991年加州第二阶段监测计划（CAMP）。CAMP的硬质底质监测阶段作为第三阶段（1991—1995）的一部分得以延续。

注意：软基质站位的样本标签包含多组识别编码，分别对应站位编号、样本类型、重复批次与分析类型，具体规则如下：站位编号范围为001至200；BSS代表底质沉积物单样（即无重复采样的站位）；BSR代表底质沉积物重复样（该站位采集了三份重复样本）；BSV代表底质沉积物变异样（子样本）；重复批次范围为01至09；TX代表分类学样本。带有BRA标识的样本标签，代表硬质底质调查中采集的岩石样本。
