“…Conversely, the Cyclone Pabuk that occurred on 1 January 2019 had been affected differently. This cyclone was initially formed in the central South China Sea at southern latitudes 5 0 [19]. It then strengthened and reached the Gulf of Thailand on 2-4 January 2019, with a maximum SWH of 8 meters.…”

A limited number of marine meteorological instruments for making observations in Indonesian waters are problems in verifying the BMKG-OFS model. The satellite altimetry was selected as a verification tool due to its wide measurement range. The verification was carried out by adjusting the coordinates, time, and grid of SWH obtained and orbit of the satellite path from the satellite altimetry to the model and overlaying the models' results as a pattern analysis in July 2018 -June 2019. The next step was a statistical analysis to determine the performance of the model. The analysis obtained 43% maximum SWH formed due to the low-pressure centers in the Pacific Ocean. The remaining spreads across the South China Sea, Indian Ocean, Andaman Sea and the Gulf of Australia. This study revealed that the SWH values from satellites were higher than the model. On every three hourly and monthly bases, the SWH of the bias, RMSE, and correlation coefficient were equivalent. The lowest bias of 0.26 occurred at 9.00 UTC, the lowest RMSE of 0.48 occurred at 21:00 UTC, and the maximum correlation coefficient of 0.82 occurred at 18:00 UTC. Whereas on a monthly scale, the lowest bias and RMSE, and the maximum correlation coefficient occurred in November. Based on these results, the BMKG-OFS model can be used to predict SWH in Indonesian waters. Besides, this verification technique can be an alternative as a new tool to verify maritime weather in the operational of BMKG.

“…These habitats have low to moderate wave energy, moderate to high water flow, moderate to high turbidity, and low irradiance, all conditions favorable for A. cervicornis (Done 1982; D'Antonio et al 2016; van Woesik et al 2020). In contrast, outplanted A. cervicornis in the shallow forereef locations are exposed to higher levels of light and wave energy that cause bleaching and damage from storm‐driven surge (Safuan et al 2020; Stainbank et al 2020; van Woesik et al 2021). Although within‐site placement of the outplants was not directly addressed as a part of this study, sites with the highest values of TLE live were those with outplants situated within sections of the forereef that were deeper than the reef crest or within hardbottom surrounding the spur formations.…”

The degradation of coral reefs has resulted in the expansion of coral reef restoration projects worldwide. In the tropical western Atlantic, most restoration efforts focus on outplanting Acropora cervicornis, once a dominant reef‐building branching coral, now found predominantly in spatially isolated populations. Hundreds of thousands of A. cervicornis colonies are outplanted onto degraded reefs every year; however, long‐term growth and survival data of outplanted corals is limited. In this study, we assessed the long‐term restoration of A. cervicornis by determining the relationship between surviving outplant populations and restoration effort. We surveyed coral populations at 11 sites in the upper Florida Keys that represented a gradient of restoration effort, defined by the total number of outplants, number of outplanting years, and time since last outplanting. We found a negative relationship between the amount of A. cervicornis live tissue and time since last outplanting, suggesting that outplants are not surviving longer than 2 years. In addition to restoration effort, we investigated how past and present benthic community metrics such as coral density and diversity may influence long‐term outplant survival. We found a positive relationship between the amount of live A. cervicornis tissue and pre‐restoration coral density, suggesting that areas that previously supported dense populations of corals may facilitate restoration success. Ultimately, this study finds that restored A. cervicornis populations decline over time, and continued outplanting effort is needed for the persistence of the species in certain areas. This study also highlights the need for more long‐term monitoring to inform adaptive management and restoration strategies.

“…Data were collected using the maximum entropy algorithm (MaxEnt) to develop a model of future habitat suitability for a specific organism, Acropora spp., that serves as a bioindicator of coral reef distribution in Maluku Waters. The selection was based on the dominance of this species as a reef builder, particularly in tropical regions (Roff, 2020;Safuan et al, 2020). Distribution data for Acropora spp.…”

Importance of the work:The sustainability of coral reefs in the Maluku Waters, Indonesia is threatened by future coastal pollution and climate change. Thus, it is crucial to develop a mapping projection model as a baseline for conservation policies. Objectives: To develop a habitat suitability prediction model for coral reefs in 2050, considering climate change scenarios and the cumulative impacts of water pollution. Materials & Methods:The model utilized the habitat data of Acropora spp. from the Ocean Biodiversity Information System database and projected them using the maximum entropy algorithm (MaxEnt) based on environmental factors (temperature, salinity, current, chlorophyll, particulate organic carbon, particulate inorganic carbon, nitrate, phosphate and ultraviolet penetration). Results:The study revealed a significant decline in spatial areas with high habitat suitability, decreasing from approximately 3,661 km² to only 64-226 km² in 2050 under the representative concentration pathway (RCP) scenarios 2.6, 6.0 and 8.5 Inter-governmental Panel on Climate Change AR5 projections. Chlorophyll concentration, an indicator of coastal pollution, had the highest correspondence with optimal coral habitat, followed by temperature and salinity. Main finding: Besides contributing to international carbon emission reduction efforts, reducing coastal water pollution runoff is crucial for supporting the long-term sustainability of coral reefs, as indicated by the model's findings. This is due to the destructive effects of water pollution and future climate change. Policy adjustments and local wisdom are essential for conserving coral reef ecosystems.
