The Sulu-Celebes Seas region covers the tri-boundary area of the Philippines, Malaysia and Indonesia. The 1918 Celebes Sea earthquake occurred on 15 August at 12:18 UTC near the Moro Gulf coast of Mindanao. Use the link below to share a full-text version of this article with your friends and colleagues. Objects, Solid Surface Sequential maps of sea surface height field from 8 November 2009 to 12 February 2010. 544.3 km depth. The change of declination of the high-temperature component shows that the Celebes Sea was rotated counterclockwise about 60° during Eocene and Oligocene time. The result that the 40‐ to 60‐day oscillation effect weakens in the downstream Makassar Strait is likely related to the dissipation of 40‐ to 60‐day eddies when they reach the western boundary of the CS and have to squeeze into the narrow Makassar Strait (recall Figure 6). From Figure 2, it is clear that the ECCO2 state estimate captures faithfully the observed ENSO‐induced large‐scale circulation variability in the tropical western Pacific Ocean. attempted incidents of abduction of crew from ships while underway in the Sulu-Celebes Sea and eastern Sabah region. Decadal Variations of the Mindanao Current During 1960–2010. The correlation coefficient between the spatial patterns is r = 0.89 and that between the PC time series is r = 0.94. The strong air‐sea interaction surrounding the Maritime Continent exposes the CS to intense regional wind forcing of monsoons and Madden‐Julian Oscillations (Madden & Julian, 1994; Zhang, 2005). Celebes Sea Sulu Sea BRUNEI MALAYSIA Mindanao North Kalimantan STRAITS TIMES GRAPHICS Sabah. The linear correlation coefficient between the black and green lines in Figure 10d reaches r = 0.72, comparable to the r = 0.76 value obtained in Figure 10c. Composition and Structure, Atmospheric The seas of Southeast Asia, which include the South China Sea (SCS), the Gulf of Thailand, the Indonesian Sea and the Sulu-Celebes Sea,1 host 1390 offshore platforms for hydrocarbon production. What cities are in Baca County Colorado, Where is Arapahoe County Colorado? Scale: Scale [ca. Continuation of the ITF entering the Makassar Strait and retroflection of the New Guinea Coastal Current from south of the equator to merge with the Mindanao Current and form the NECC are both discernible in Figure 1. The Philippines is a country of 7,107 islands located in southeast Asia. This repeat cycle aliases the semidiurnal M2 tides, for example, into the 62.1‐day altimeter‐derived sea surface height [SSH] signals [Ray, 1998].) Given the modest correlation between the salinity anomaly signals and, Black lines: Salinity anomaly time series in (a) the Celebes Sea and (b) the Makassar Strait entrance (same as the black lines in Figures, Journal of Advances Online Versions: National Library of Australia digitised item; Edition: Large corrections to 1887. Consistent with Figure 5, it reveals significant kinetic energy level fluctuations on the interannual time scales. The Celebessee (or Sulawesi Lake) is a 472,000 km2 marginal sea of the Pacific Ocean … In the east lies the Pacific Ocean, in the Northeast the Philippine Sea and in the north the Sulu archipelago, which is the border to the Sulu Sea. With the CS eastern boundary located near 126°E, Figure 5 reveals that the intraseasonal variability inside the CS basin of 118°E–126°E is distinct from that in the open Pacific Ocean east of 128°E. This study is supported by the National Natural Science Foundation of China (grant 41706004), the Natural Science Foundation of Jiangsu Province (grant BK20170872), the Fundamental Research Funds for the Central Universities (grants 2017B04614 and 2017B04114), the National Natural Science Foundation of China (grants 41522601 and 41776004), the Natural Science Foundation of Jiangsu Province (grant BK20170870). Since it is constructed in a dynamically and thermodynamically consistent way (see section 2) and produced adequately the intraseasonal eddy variability inside the CS, the ECCO2 state estimate is well suited to explore the interannual modulations of the CS 50‐day oscillations. What is Rehoboth Beach known for? Clearly, future studies are needed to clarify these processes for a better understanding about the ITF impact by the 40‐ to 60‐day oscillations initiated in the CS. Not surprisingly, the SSH difference, hN(t) – hS(t), time series shown in Figure 10c by the solid line compares favorably with the I50d time series (the dashed line in Figure 10c). The Sulawesi Sea covers an area of 400,000 km2, with mean water depth of somewhat over 5 km and crustal thickness of about 6-7 km (Murauchi et al., 1973). The Philippine Sea lies along the east coast of the country while the South China Sea is to its west. Your email address will not be published. Geophysics, Geomagnetism 608.8 km depth. Nearby countries include Indonesia, Malaysia, Brunei, and Singapore. What cities are in Elbert County Colorado, Where is Eagle County Colorado? (1896-1977), Chinese Journal of Geophysics (2000-2018), International View of Mataking Island. Intersect of IHO Sea Areas and Exclusive Economic Zones (version 4) (look up in IMIS) Celebes Sea IHO 23-3rd: Limits of Oceans and Seas, Special Publication 23, 3rd Edition 1953, published by the International Hydrographic Organization. Despite this weakening, an analysis of the mooring observations across the Labani Channel by Pujiana et al. This map shows the location of the Philippines within Asia, specifically Southeast Asia. An examination of water mass property changes indicates that the 40‐ to 60‐day oscillation modulations affect the salinity‐maximum Tropical Water inside the CS and Makassar Strait. and Paleomagnetism, History of Comparison between the Celebes Sea 50‐day oscillation index (red line) and the 1.5‐year low‐pass filter principal component (PC) of empirical orthogonal function mode 2 of sea surface height anomalies from the Estimating the Circulation and Climate of the Ocean, Phase II (ECCO2) product (black line). Black line shows the interannual signals after a 1.5‐year low‐pass filtering. There are three objectives in our study. A zonal SSH ridge along ~9°N appears, however, more pronounced in the ECCO2 EOF result than AVISO data. While this represents more than double the number of platforms in the North Sea2, they are spread over the many meanders in the seas of Southeast Asia. Mean sea surface height (colors) in the western Pacific based on satellite altimetry observations. (2015). The earthquake's epicenter (marked with a star icon on the map) was located near the towns of Rizal and Bongabon in Nueva Ecija. Felt Report - Tell Us! While our basic understanding of the 50‐day oscillations inside the CS is established, lack of sustained long‐term observations has precluded studies in the past to examine the interannual changes of the intraseasonal oscillations inside the CS. The long‐term freshening trend seen in Figure 13b is also consistent with the overall increasing trend in I50d. According to the 1982 United Nations Convention Law of the Sea (UNCLOS), piracy is defined as ‘illegal acts of violence, detention or depredation, committed for private ends by the crews or passengers of a … The AVISO SSH data have a 1/3° × 1/3° horizontal resolution and a 7‐day temporal resolution. Celebes Sea The Celebes Sea of the western Pacific Ocean is bordered on the north by the Sulu Archipelago and Sulu Sea and Mindanao Island of the Philippines, on the east by the Sangihe Islands chain, on the south by Sulawesi 's Minahasa Peninsula, and … To some degree, it may not be surprising that the dominant ENSO‐induced variability is fully captured by ECCO2. By 20 million years ago, earth crust movement had moved the basin close enough to the Indonesian and Philippine volcanoes to receive emitted debris. Where is Sharp County Arkansas? What cities are in Arapahoe County Colorado, Where is Adams County Colorado? To clarify the dynamical processes behind the interannual modulations of 40‐ to 60‐day oscillations inside the CS, we regress the ECCO2 SSH and surface velocity anomaly fields to the 50‐day oscillation index I50d (see Figures 8a and 8b). CELEBES SEA: Date time: 2021-01-07 16:48:16.0 UTC: Location: 3.96 N ; 123.47 E: Depth: 74 km: More details: Map of testimonies: View testimonies on interactive maps; Witness location : Zamboanga (Philippines) (361 km NW from epicenter) Time : T0+ 2 min . CS is an important gateway that connects the Pacific and Indian Oceans. (c, d) Same as (a, b) except from the Estimating the Circulation and Climate of the Ocean, Phase II (ECCO2) simulation. Interval between each map is 12 days. For high‐pass filtering, we utilize the MATLAB built‐in function filtfilt (b,a,input‐timeseries), where [b,a] = butter (10,1/(100/3)*2,‘high’). A very similar salinity variability is detected in the 75‐ to 175‐m layer at the entrance of the Makassar Strait at 119°E–120°E and 1°N (Figure 14). 7; Click the Bay of Bengal Countries 7; Mirrored Asia 6; Click the Red Sea Countries 3 2020-06-03 20:13:47 (UTC) | 4.687°N 122.747°E | 608.8 km depth As can be identified in the PC time series, the EOF mode 2 represents the seasonal SSH changes that modulate interannually in the tropical western Pacific Ocean. , adding the contribution from the ENSO variability increases the correlation coefficient to r = 0.79 only. Physics, Solar The entirety of the Sulu Sea is Philippine internal waters and the majority of the incidents occur within, or in close proximity to Territorial Waters. It is worth noting that the 50‐day oscillation index corresponds well to the interannual signals captured in the EOF mode‐2 PC time series of Figure 3d. The border between Indonesia and the Philippines consists of a maritime boundary mainly on the Celebes Sea that separates the two Southeast Asian countries as defined through a pact that was signed by both parties in 2014. The Inner Space Speciation Project expedition began in the port of Manila (top center) and went south through the Sulu Sea to a study site southeast of the Sulu Archipelago, where the ocean bottom falls off abruptly to the seafloor thousands of meters below. What cities are in Weld County Colorado, Where is Teller County Colorado? Data Download. It had a magnitude of 8.3 on the moment magnitude scale and a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. This is so because in situ measurements inside the CS are rare and satellite altimetry measurements, which have been utilized broadly in regions where in situ measurements are lacking, have issues of tide aliasing in marginal seas such as the CS. The change of declination of the high-temperature component shows that the Celebes Sea was rotated counterclockwise about 60° during Eocene and Oligocene time. Volume 27, Issue 3, 25 February 1999, Pages 309-325, 25 February 1999, Pages 309-325 Celebes Beach Resort is a new secluded two stars resort located in the Celebes Sea. (. We thank the two reviewers for their detailed and constructive comments that helped improve an early version of the paper. View of Mataking Island. What cities are in Mesa County Colorado, Where is Las Animas County Colorado? It had a magnitude of 8.3 on the moment magnitude scale and a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. Specifically, during the mature phase of El Niño events, the western Pacific SSH anomaly tends to have a high‐low‐high tripolar meridional structure, reflecting the intensification and northward expansion of the NECC and North Equatorial Current (e.g., Chen et al., 2016; Qiu & Lukas, 1996; Zhao et al., 2013). What cities are in Teller County Colorado, Where is Summit County Colorado? Compared to a basin‐averaged EKE level of less than 0.02 m2/s2 in weak oscillation years, the active oscillation years in 1993, 2002–2003, 2006–2010, and 2013–2015 had an EKE level exceeding 0.04 m2/s2. As such, before exploring the dynamical processes governing the interannual modulations of eddy variability inside the CS, it is important to verify the broadscale oceanic variability surrounding the CS in the ECCO2 state estimate against the available satellite altimetry measurements. To examine the effect of the 40‐ to 60‐day oscillation signals upon the water masses more quantitatively, we plot in Figure 13a the vertical salinity profile as a function of time at a center location (122°E–123°E, 3°N–4°N) inside the CS.
