Description

Stream invertebrates were surveyed at a series of sites on Macquarie Island, established in 1992 by Richard Marchant (Museums Victoria) under ASAC_555. At each site, five replicate kick samples were collected and taxon sorted and scored as presence/absence by R. Marchant. For 1992, these replicate-level data are available electronically (ASAC_555 metadata record .csv file), but for subsequent surveys in 2008, 2010 and 2016, the digitised data were entered as the sum of the five replicate samples for each site (values 0-5). These latter data were collected under ASAC_2918 (Nugegoda; 2008), AAS_3261 (Kefford; 2010) and AAS_4305 (Shaw; 2016). The data provided with this record are PDF file scans of the original hard copy, hand written, score sheets prepared by Richard Marchant as a record of replicate-level presence/absence data. Each sheet includes:

- Top Left corner = sample collection date (year and month/s)
- Column 1 = taxa names (as provided in digitised records)
- Header row 1 = site#replicate (e.g. 2#1, 2#2, 2#3, 2#4, 2#5 = site 2, replicates 1-5)
- Presence = tick
- Absence = empty cell

Other feint notes can be disregarded, these are additional notes made by R. Marchant during sample processing that relate to the general condition of the samples.

Purpose

Provide a scanned copy of original hard copy, hand written, score sheets prepared by Richard Marchant as a record of replicate-level presence/absence data. Digitised data for 2008, 2010 and 2016 are entered as sum of five replicate samples for each site (values 0-5) and are therefore missing replicate-level detail.

Quality

The scanned images are faint, but ticks (indicating presence of a taxa in a sample) are legible. Additional feint notes can be disregarded, these are additional notes made by R. Marchant during sample processing that relate to the general condition of the samples.
