UNACOMODELI

UNESCO-Philippine National Commission (UNACOM) Online and Digital Enabling Library and Index

The UNESCO-Philippine National Commission Online and Digital Enabling Library and Index (UNACOMODELI) aims to disseminate its publications, reports, and policies and also promote the works of its national committee members.

Initially, the UNACOM Online and Digital Enabling Library and Index is developed to support the alignment of research, investments, and community initiatives toward contributing to a well-functioning, productive, resilient, sustainable, and inspiring ocean. The goal is to enable the government, partner agencies, and UNESCO to develop more robust Science-Informed Policies and facilitate a stronger Science-Policy Interface through the gathered data, information, and knowledge related to the Ocean Decade in the Philippines.

Particularly, it aims to:

  • Gather and index all publications, reports, policies, laws, legislations, articles, and other documents of the Philippine National Committee on Marine Sciences (NCMS) related to the Ocean Decade
  • Disseminate and promote these publications, reports, policies, and other documents on the initiatives and actions to address the Ocean Decade challenge

Seagrass-mangrove ecosystems management: A key to marine coastal conservation in the ASEAN region
Fortes, Miguel D. (Elsevier BV, 1991-01)
Seagrass beds and mangrove forests are intimately linked by functional interactive processes which are as yet little understood. These high-order interactions form a major basis which justifies an integrated management scheme for the two ecosystems. However, while dominating enclosed coastal areas in the ASEAN region, seagrass and mangrove habitats are being degraded and destroyed at an alarming rate, raising serious doubt on their capacity for biological sustainability and normal recovery within this generation. An integrated approach towards seagrass and mangrove ecosystems management in the ASEAN region is discussed within a framework of known ecological principles. Recommendations are made for the conservation and sustainable use of the ecosystems and their resources.

Preliminary study of the redistribution and transformation of HgS from cinnabar mine tailings deposited in Honda Bay, Palawan, Philippines
Benoit, Gaboury; Schwantes, Jon M.; Jacinto, Gil S.; Goud-Collins, Margaret R. (Elsevier BV, 1994-12)
Mining operations in Palawan, Philippines, resulted in cinnabar (HgS) mine tailings being used to build a 600 m long peninsula in Honda Bay. Samples collected from the peninsula as well as sediments from the surrounding waters had elevated mercury levels as high as 570 ppm. Natural processes are transporting mercury as much as 10 km from the peninsula, mainly in a coastwise direction, and preferentially associated with fine-grained, organic-rich sediments. Depth of penetration into sediments exceeds 10 cm near the source. As the HgS is transported away from the peninsula, it is rapidly altered to more bioavailable forms; 50% conversion occurs within a distance of only 10–40 m.

Influence of Bass Strait water on the Tasman Sea thermocline
Villanoy, C. L.; Tomczak, M. (CSIRO Publishing, 1991)
Volumetric analysis of the Tasman Sea Central Water for different temperatures and salinities was used to determine the degree of influence of the seasonal outflow from Bass Strait on the observed strong positive anomalies in the Tasman Sea thermocline. The absence of a systematic decrease of salinity and Bass Strait Water content away from the coast suggests that the observed high-salinity anomalies are not entirely manifestations of Bass Strait Water alone and that some local processes may be involved in modifying the water properties. It is suggested that the seasonal Bass Strait Water intrusions may act as a trigger to overturn the environment, entraining high-salinity water from the upper layers by double-diffusive convection.

Reproduction in Eucheuma denticulatum (Burman) Collins and Hervey and Kappaphycus alvarezii (Doty) Doty farmed in Danajon Reef, Philippines
Azanza-Corrales, Rhodora; Mamauag, Samuel S.; Alfiler, E.; Orolfo, M. J. (Elsevier BV, 1992-04)
Occurrence of reproductive structures in seven forms belonging to two species of carrageenophytes, Eucheuma denticulatum and Kappaphycus alvarezii was determined at a farming site at Danajon Reef, Northern Bohol, Philippines during 1987 and 1988. Reproductive plants of these forms were encountered throughout the study period although not all three structures (asexual or tetrasporic form and sexual male and female forms) were represented in each form. For K. alvarezii forms, taking the ‘browns’ (EAB1 and EAB2) and the ‘greens’ (EAG1 and EAG2) collectively, male and female reproductive structures were found throughout the year but no tetrasporic thalli were encountered. Only male and tetrasporic structures were observed for E. denticulatum (EDB and EDG) while the ‘sacul type’ ( EAG3 ) had both structures present throughout the study period. Analysis of variance revealed significant difference (P < 0.05) in the frequencies of reproductive structures of each form.

Optimized Agar Extraction from Gracilaria eucheumoides Harvey
Villanueva, R. D.; Pagba, C. V.; Montaño, N. E. (Walter de Gruyter GmbH, 1997)
A 33 factorial experimental design was utilized to determine the optimum alkali pretreatment conditions in the extraction of agar from Gracilaria eucheumoides. Three levels from each of three factors were considered: Temperature, 70, 80, 90 °C; NaOH concentration, 4, 7, 10% and; treatment duration, 0.5, 1, 2 h. The optimum conditions were found to be 90 °C, 10% and 2 h. The gel strength of the agar yielded under these conditions was 432 ± 43 g/cm2. The effects of the different alkali pretreatment conditions to the agar yield and 3, 6-anhydrogalactose and sulphate contents were also determined. Agar yield was higher at lower temperature, stronger alkali solution and shorter treatment duration. Higher 3, 6-ahydrogalactose content and lower sulphate level were obtained at higher temperature, higher alkali concentration and longer duration of treatment.
