Further investigations of the effects of the Nella Dan oil spill 1988/94

Metadata record for data expected from ASAC Project 1003 Further investigations of the effects of the Nella Dan oil spill on intertidal benthic communities at Macquarie Island: continued recovery of kelp holdfast communities. See the link below for public details on this project. The project investigated spatial variation in kelp holdfast macrofaunal communities 7 years after the initial oil spill. The project was expanded to cover more sites than were sampled in projects 250 (ASAC250) and 672 (ASAC672). Results indicated that an impact was still detectable at one of the 3 oiled sites. This dataset contains the 1988 and 1994 data. Holdfast data from the 1994/1995 season is also included (comparing east versus west). The numbers are total individuals of each species that were found in each holdfast sample. This is a basic, though standard, species-abundance matrix. The site codes used in this project are: SB = Sandy Bay SEC = Secluded Bay BB = Buckles Bay GC = Garden Cove GG = Green Gorge GB = Goat Bay HMB = Half Moon Bay BAUER = Bauer Bay Other codes as for oil spill data The first number given after the site code is the site number at that sampling location. The second number is the replicate at that site. Thus sb(1)3 is Sandy Bay site 1, replicate 3. The fields in this dataset are: Species Year Site Quality: 2018-08-28 - The original datasheet was reformatted to fit OBIS/GBFI/IPT Biodiversity.AQ standards. The new datasheet "DurvillaeaHoldfastAssocFauna88_94.csv" provides the data of fauna associated with holdfast of Durvillaea antarctica from Macquarie Island, samples were collected in 1988 and 1994. This new data sheet contains datasetID, occurrenceID, country, event date, decimal latitude, decimal longitude, locality, eventDate, eventRemarks, basisOfRecord, occurrenceStatus, organismQuantity, organismQunatityType, associatedTaxa and associatedReference. It also provides species identification to the lowest taxonomical rank that could be determined. Species names are matched in WoRMS (World Register of Marine Species).

元数据记录对应ASAC项目1003：探究Nella号油轮溢油对麦夸里岛潮间带底栖生物群落的影响的深入研究——海藻固着器群落的持续恢复。请通过下方链接查看该项目的公开详情。
本项目针对首次溢油发生7年后的海藻固着器大型底栖动物群落空间变异展开调查。本项目相较于项目250（ASAC250）与672（ASAC672），扩大了采样覆盖的样点范围。
研究结果显示，3个受溢油影响的样点中仍有1个可检测到显著影响。
本数据集包含1988年与1994年的采样数据，同时纳入了1994/1995季的固着器采样数据（用于对比东西两侧样点的群落差异）。数据记录为每个固着器样本中各物种的总个体数，属于基础且标准的物种-多度矩阵。
本项目使用的样点代码如下：
SB = 桑迪湾（Sandy Bay）
SEC = 隐蔽湾（Secluded Bay）
BB = 巴克尔湾（Buckles Bay）
GC = 花园湾（Garden Cove）
GG = 绿色峡谷（Green Gorge）
GB = 山羊湾（Goat Bay）
HMB = 半月湾（Half Moon Bay）
BAUER = 鲍尔湾（Bauer Bay）
其余代码与溢油数据所用代码一致。
样点代码后的第一个数字代表该采样点位的样点编号，第二个数字代表该样点的重复采样次数。例如sb(1)3即代表桑迪湾样点1，重复采样3次。
本数据集的字段包括：物种、年份、样点。数据质量更新日期：2018-08-28——原始数据表已重新格式化，以符合OBIS/GBFI/IPT Biodiversity.AQ标准。
新数据表《DurvillaeaHoldfastAssocFauna88_94.csv》收录了采自麦夸里岛、与南极牛海带（Durvillaea antarctica）固着器相关的动物群落数据，采样时间为1988年与1994年。该新数据表包含datasetID、occurrenceID、国家、事件日期（event date）、十进制纬度、十进制经度、采样地点、eventDate、eventRemarks、basisOfRecord、occurrenceStatus、organismQuantity、organismQuantityType、associatedTaxa与associatedReference。同时，该数据表已将物种鉴定至可确定的最低分类学阶元，物种名称均匹配世界海洋物种登记册（World Register of Marine Species，WoRMS）中的标准条目。
