Fig. 1.2. Variation in pH levels in the world oceans (Donney, 2006).

Fig. 1.3. Changes in aragonite saturation of the world's oceans(Feely et al., 2009).
Aragonite saturation is measure of CO3-2. It is used to
track ocean acidification.

Proj. 1c – Monitoring Biodiversity at NIPAS Sites and Ocean Acidification Baseline Study
Draft pH mapDraft Aragonite saturation map
Biodiversity Ocean Acidification Baseline Study
Main Objective• To monitor biodiversity and determine baseline information on carbonate
parameters at 5 NIPAS sites
(using Autonomous Reef Monitoring Structures or ARMS)
(pH and aragonite saturation maps)
KEY QUESTIONS i. Is there a difference in natural biodiversity among the 5 NIPAS sites?ii. Within a site, does diversity differ in the context of varying levels of environmental
disturbance/stress?iii. Within a site, does diversity differ in an area with distinct physical features (e.g. CO2
venting site) compared to an undisturbed area?iv. Is there a pattern of spatial and temporal differences in distribution of species/
operational taxonomic units? Is there a correlation between diversity patterns and physical parameters (ocean acidification)?
Biodiversityo 45 ARMS units deployed in 5 NIPAS
siteso deployment of temperature and light loggers
onto ARMS, except in Tubbataha)
o A total of 68 individuals received lecture on ARMS and 27 individuals trained on ARMS deployment
o Website on ARMS created (ARMS Philippines facebook page)
Ocean Acidificationo Spatial and temporal (24-hr) data on
carbonate parameters (pH, aragonite saturation, etc.) in 5 NIPAS sites

Tentative Plan for WESTPAC OA Programme Implementation in the Pilot
Sites for the Next Phase
• Revisit some pilot sites for carbonate chemistry• Retrieve ARMS deployed in protected area sites• Start a research program in 2018 to study coastal
acidification and its effects

Challenges, Strengths and Lesson-learned from Implementing the SOPs and the
WESTPAC –OA Programme
• Securing government support to do OA research has not been easy Why?
- poor understanding of OA - problem seen as too remote- Philippines as very minor contributor
of CO2
Visions/ideas on the Way Forward for the WESTPAC OA Programme
• Synthesis of information to better describe status of OA in the region
• All WESTPAC partner countries capable of monitoring and studying OA
• Regional agreement/policy to help address OA issues in the region
Participant/Institute/Country roles in the Joint Regional OA Programme
• Provide inputs and insights on OA monitoring and research
• Training of researchers who want to start OA work
