Abstract:

Temperature loggers (HOBO) placed in two locations (HOBO1: 10.74373, 124.78668, HOBO2: 10.74364, 124.78665) off the coast of the West coast of Leyte, the Philippines , 2012-2019.

Methods & Sampling

Two HOBO temperature loggers were set and replaced annually 2012-2019 at two locations, HOBO1 (10.74373, 124.78668), HOBO2 (10.74364, 124.78665), off the coast of the West coast of Leyte, the Philippines. Loggers were recovered and swapped annually.

The two devices took readings 15 minutes apart, and each took readings every 30 minutes, for a combined reading every 15 minutes. The loggers are spaced 10.5 m apart in a NW orientation. They are 80m offshore and tethered to the seafloor at a depth of ~4m (varies with tide).

Issue Report: The 2014 loggers were never recovered due to being displaced by Typhoon Yolanda. There are no data from 2014 in this dataset.

There are gaps in the temperature in this dataset that mark times when the loggers started and stopped, which can be seen as null values in the "Temp" column in the data table.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* Data Version 1: individual csv files collected into file bundles and added to the datset in the "Data Files" section. They could not be combined into one table for this dataset due to inconsistency amongst the files in temperature (C or F) and time zones.
* Dataset version 2 [2023-03-06] replaces dataset version 1. Version 2 includes a combined data table with consistent time zone and formatting across the entire dataset. The original hobo files are still attached in addition to the combined table.

File
Temperature Loggers filename: temp_loggers.csv (Comma Separated Values (.csv), 14.20 MB) MD5:bed56b28f36c37a6a93d41e2bc582a0d This is the main data table for this dataset and combines data from several hobo temperature loggers. Date and time are provided in consistent timezones and formats across the entire data table. See "Parameters" section for detailed column information.

CSV files from hobo loggers (by year and site) which contain deployment and manufacturer-specific information in the file headers.  See file headers for individual parameters since time zone varies amongst the files, and they will be either temperature in C or F.   The serial number of the instrument is also contained in the file header.
