Catch Logs from LHP Cruises

Description of the core columns that persist throughout OES bottomfish sampling datasets.

While the data have not changed from previous InPort records (see Nodes 11630, 11652), this is part of an effort to standardize and streamline all life history program databases for past and future cruises. This data set includes separate catch logs from each LHP Bottomfishing cruise both within and outside of the Main Hawaiian Islands, as well as a master file with all records.

Interested parties should note that individual cruises may/may not have collected extraneous information on the data sheet that is NOT conserved in this streamlined edition. Please contact the data steward if there is a certain value (such as bait and hook use or fishermen involved) that you are interested in that does not appear here. These are retained in the original datasets but removed from the consolidated version made available to the public.

Original documents, copies and electronic files are stored at the IRC.

SE-16-01 Samoa and Western Samoa Directory & R Project

Consolidated by M Kapur 13 May 2016

maia.kapur@noaa.gov

NOTICE: THE DATA FILES IN THE 'DATA' DIRECTORY ARE LINKED TO A RELATIONAL DATABASE IN MS ACCESS.

MODIFICATIONS THEREOF WILL BE REFLECTED IN THE OVERALL DATABASE.

This folder has raw and cleaned data recorded on SE-16-01 from Mar to Apr 2016.

The 'code' folder is a growing compilation of scripts used to clean and visualize catch data from this cruise.

SE-16-01 Samoa catchLog.xls:

Each record (row) represents an single fishing outcome for a given drop.

Drops with multiple fish caught result in duplicate records.

Data were entered by Maia Kapur on 05 - 10 May 2016.

GPS coordinates, as recorded by fishermen, were converted within excel to Decimal degrees

with the following formula:

(Hours + Minutes/60) * -1 ; ensuring that the "minutes" are comprised of a FLOAT value.

The CSV version of this sheet is entitled "catch.csv".

Notes:

Certain crew did not record depth in fathoms for their trips.

Wherever possible, species names have been substituted by four-letter codes.

See "Spp Code" sheet in /Data for conversion key.

Location was designated based on what was indicated for that date

on the Bio Sampling data sheet, and is therefore approximate.

SE-16-01 Samoa bioSampling.xls:

Each row represents a single processed fish and its respective data number (beginning in SE-16-01) which will

follow through histology and aging. The Zip Tie # connects it to the Catch dataset.

The 'spurious' tab indicates records that are likely incorrect.

The CSV version of this sheet is entitled "raw.csv".

Notes:

Some fish were saved for outreach or left unprocessed, and thus have no ZipTie number.

Many such species did not undergo gonad extraction or other measurements.

The affiliated R Projects detail the QA/QC procedures used to check data for typographical errors

and possible outliers. Users are advised to use spatial visualization tools (eg GIS) to ensure that

GPS coordinates are accurate within the catch log; and graphical tools in R to check for outlier points

in life history parameters. Because SPP codes can only be verified by hand, we recommend checking ~20% of entries

for accuracy.

PIFSC ITS performs scheduled backups.

This data were entered by various personell, typically M Leuers/Sundberg or M Kapur following collection on LHP cruises beginning in 2008. This data was sourced from data sheets filled out by fishermen and scientists aboard the ship or small boats. In May of 2016 M Kapur took over as data steward and metadata specialist for this and all LHP program databases.
