<p>The Western Pacific Warm Pool (WPWP) as a major source of heat and water vapor has a crucial influence on climate dynamics both in the tropics and globally. Yet, there is conflicting proxy evidence regarding the evolution of WPWP temperatures since the Miocene. On the one hand TEX<sub>86</sub> data suggest a gradual cooling by ~2℃ (O’Brian et al., 2014, Zhang et al., 2014) from the Pliocene to today, while faunal (planktonic foraminifera) sea surface temperature estimates (Dowsett, 2007) and Mg/Ca data measured in planktonic foraminifera (Wara et al., 2005) on the other hand indicate the absence of any long-term temperature trends. It has been suggested that Mg/Ca temperatures could on these time scales be biased by long-term changes of the Mg/Ca ratio of seawater (Evans et al., 2016). To test the influence of the proposed seawater changes on Mg/Ca we combined data from two independent temperature proxies, Mg/Ca and clumped isotopes, measured on two species of planktonic foraminifera from IODP Site U1488 in the central WPWP. Our study finds good agreement between both proxies thereby verifying the validity of Mg/Ca records from the WPWP and confirming the absence of a Plio-Pleistocene cooling trend for the WPWP. This finding suggests that the persistent disagreement between foraminifer-based proxies such as Mg/Ca and biomarker data might be caused by different environmental parameters being recorded in the two archives.</p><p> </p><p>References:</p><p>O’Brien CL, Foster GL, Martínez-Botí MA, Abell R, Rae JWB, Pancost RD.

Hot Event merupakan fenomena suhu permukaan laut (SPL) tinggi lebih dari 30°C dan memiliki mekanisme khusus dalam pembentukannya, yaitu kecepatan angin lemah dan radiasi matahari tinggi. Hot Event memiliki peran penting dalam menyumbang bahang pada pacific warm pool di Samudra Pasifik bagian barat dan berperan mengatur variasi iklim global. Indonesia sebagai negara kepulauan memiliki potensi besar melemahkan sirkulasi angin dan potensi kejadian Hot Event. Selat Malaka merupakan selat terpanjang di Indonesia dan berpotensi untuk menjadi area kajian Hot Event. Fenomena SPLtinggi (>30°C) dan konstan selama 13 tahun (2003 – 2015) di Selat Malaka merupakan hal unik untuk dikaji. Penelitian ini bertujuan untuk mengidentifikasi dan mengetahui mekanisme terjadinya SPL tinggi (>30°C) dan konstan selama 13 tahun (2013 - 2015) di Selat Malaka. Metode yang digunakan adalah metode kuantitatif. Data yang digunakan adalah data harian SPL, angin, arus permukaan, radiasi matahari selama 13 tahun serta batimetri. Pengolahan data menggunakan bahasa pemograman untuk memvisualisasi SPL tinggi >30°C, angin lemah <2 m/det, arus, radiasi matahari tinggi 200 W/m² serta data batimetri. Variasi SPL paling tinggi dan konstan terjadi pada musim timur (Agustus) dan paling rendah pada musim barat (Februari). Fenomena SPL tinggi dan konstan di wilayah kajian B terhadap kajian A dan C disebabkan lemahnya kecepatan angin <2 m/det di wilayah B dibandingkan wilayah A dan C, serta didukung dengan tingginya radiasi matahari dan batimetri wilayah kajian B yang relatif dangkal, sehingga proses pemanasan massa air lebih cepat dibandingkan wilayah kajian lainnya.  Hot Event is a phenomenon of high sea surface temperature (SST) over 30 °C and it has a unique mechanism in its formation by the lower wind speed and high solar radiation. Hot Event has an important role in contributing heat to the pacific warm pool in the western Pacific Ocean and play a role in regulating global climate variations. Indonesia as an archipelagic country has the potential to weaken wind circulation and potential Hot Event. The Malacca Strait is the longest strait in Indonesia and it is potential for Hot Events. The phenomenon of high SST (>30 °C) and constant for 13 years (2003 - 2015) in the Malacca Strait is unique to be studied. The present research aims to identify and determine the mechanism of the occurrence of high SST (>30 °C) and constant for 13 years (2013 - 2015). The method used in this study is quantitative method. The data used are daily data of SST, wind, surface currents, solar radiation for 13 years, and bathymetry. Programming was used to visualize high SST >30 °C, lower speed winds <2 m/s, currents, high solar radiation 200 W/m² also bathymetry data. The highest and constant variation of SST occurs in the east season (August) and the lowest in the west season (February). The phenomenon of high and stable SST in area B on A and C is due to the low wind speed <2 m/s in region B compared to A and C and it is supported by high solar radiation and shallow bathymetry in area B, so that the heating process of water mass is faster than other areas.
