Field seasons (SCUBA) in Leyte, Philippines to study coral reef fish resilience.
Location: West coast of Leyte, Philippines in the municipalities of Albuera (10.91667, 124.69667) and Bay Bay City  (10.676940, 124.799170)

 Fish and invertebrate surveyor procedure:

- records dive and transect attributes:

- dive number

- transect number

- site name

- date

- time

- observer initials

- visibility (meters)

- depth at start of transect (feet)

- depth at end of transect (feet)

- transect length (meters)

- transect width (meters)

- expected transect duration (minutes)

- swim the length of a 25m by 5m transect in 20 minutes and record all fish (>2 cm, non-cryptic) within transect bounds

- swim back along the length of a 25m by 5m transect in 10 minutes and record all invertebrates within transect bounds

- record any additional notes

Instruments:
SCUBA gear (mask, tank, regulator, wetsuit, fins, dive computer)
Waterproof paper
Pencil

BCO-DMO Data Manager Processing notes:
* Imported data tables each sheet named "FishInvert" within files submitted to BCO-DMO as Transect_and_quadrat_data/GPSSurveys.*.xlsx
* supplemental transect locations table from Transect_locations/Transect_locations.*.xlsx concatenated together and attached to this dataset and Benthic Cover dataset as a supplemental file.  See the file description for details about one location lat/lon that was updated based on a comment in the file.
* Taxon and ID codes for Fish, anemone, and invertebrates added as a supplemental file from codes in "Codes" sheet of GPSSurveys.*.xlsx.  Tail and "Clown" codes were not used here, but can be found as part of the related "Clownfish photo" dataset and log.
* replaced semicolons in time values to colons to match the rest of the time format.
* Column Image_nums listed file image numbers delimited with either a space, comma, or comma and space.  Changed to semicolon delimiter for consistency.
* Date format changed to ISO 8601 format YYYY-MM-DD
* Column ISO_DateTime_UTC added to data table from local dates and times.
* After consultation with the data submitter, null values in count colunms were changed to 0 values since that is the correct value to use. Columns updated (Num_0_5  Num_5_10  Num_10_15  Num_15_20  Num_20_25  Num_25_30  Num_30_35  Num_35_40  Num_40_45  Num_45_50  Num_50_55  Num_55_plus).

Description from NSF award abstract:
When Typhoon Haiyan hit the Philippines it had sustained winds of 305 to 315 kph and was the strongest storm ever to make landfall. Storms are one of the most important disturbances to coral reef ecosystems. Previous research has primarily emphasized that habitat recovery is important for the recovery of reef fish communities after disturbance. We understand little, however, about the role of larval dispersal in mediating species responses to disturbance. Reef fish function as metapopulations connected by larval dispersal among reefs, and larval connectivity is therefore a critical process for their dynamics. A field site directly in Typhoon Haiyan's path provides an ideal opportunity to address the role of larval dispersal during recovery. Over the course of four field seasons (2008 to 2013), nearly two thousand clownfish were surveyed along 20km of coastline. Clownfish possess the same basic life history as most reef fish (sedentary adults and pelagic larvae), but are sufficiently rare and visible that genetic parentage methods can be used to follow larval dispersal. This study site is therefore a unique location in which to understand the metapopulation impacts of a massive storm. This project will focus on three hypotheses: 1) Habitat destruction determines the short-term impacts of storms disturbance, 2) Metapopulation processes shape recolonization after disturbance, and 3) Disturbance allows rare competitors to increase in abundance. The project will address these questions with a combination of fixed and random transects to assess reef habitat and reef fish abundance and diversity, as well as detailed, spatially explicit surveys of anemones and clownfish. Genetic mark-recapture and parentage methods with yellowtail clownfish will pinpoint the origin of new recruits that recolonize the reef post-typhoon.
