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. We can create the map for you! (1896-1977), Chinese Journal of Geophysics (2000-2018), International 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. What cities are in La Plata County Colorado, Where is Kit Carson County Colorado? Finally, we discuss the impact of the interannual modulations of the CS intraseasonal variability upon the water mass properties of the ITF. Location of the Celebes Sea on the world map. What cities are in Garfield County Colorado, Where is Fremont County Colorado? Modulated by the activity of eddy sheddings, the upper ocean water mass properties in both the Celebes Sea and Makassar Strait exhibit noticeable interannual changes with less saline waters appearing in the 75‐ to 175‐m layer during the active eddy shedding years. What cities are in Summit County Colorado, Where is Sedgwick County Colorado? The ECCO2 state estimate has been used in the past to examine the eddy variability in different parts of the global ocean (e.g., Chen et al., 2014; Fu, 2009; Qiu et al., 2017; Zemskova et al., 2015). 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 do so, we plot in Figures 10a and 10b (solid lines) the low‐pass filtered SSH anomaly time series hN(t) and hS(t) in the box (128°E–145°E, 8°N–12°N) and (128°E–145°E, 3°N–7°N) north and south of the dipolar SSH boundary, respectively. Red lines in (b) and (d) indicate Niño‐3.4 index. Figure 1 compares the 1993–2016 time‐mean surface circulation distributions in the tropical western Pacific Ocean: The vectors show the surface velocity field from the ECCO2 output, and the colored contours represent the AVISO SSH field. Only shallow, warm, and less saline water flows from the Sulu Sea into the Celebes Sea, so that incoming water doesn’t mix with the deep water of the Celebes Sea, either. To verify aspects of the ECCO2 state estimate in the region of our interest, we use in this study the merged SSH anomaly data distributed by Archiving, Validation, and Interpolation of Satellite Oceanographic (AVISO) data (http://www.aviso.oceanobs.com/) that combines simultaneous measurements from two satellite altimeters (TOPEX/Poseidon or Jason‐1 and ERS or Envisat). This makes combating the threat … Unlike mode 1, the EOF mode‐2 SSH pattern has a dipolar meridional structure and it reflects the meridional shift of the NECC on the seasonal time scale. Inside the CS basin and the Makassar Strait, there exists a clear negative value, indicating that as the level of 40‐ to 60‐day eddy activity increases, more North Pacific‐origin fresh water tends to penetrate into the CS and its downstream region.

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). Decadal Variations of the Mindanao Current During 1960–2010. The Molucca Sea has a total surface area of 77,000 square miles (200,000 square km). Geophysics, Biological Southward shifting of the wind‐driven North Pacific tropical gyre and the concurrent strengthening of the Mindanao Current southeast of the Mindanao Island in these years are found to be inducive for the generation of cyclonic eddies intruding into the Celebes Sea. Since our defined 50‐day oscillation index reflects the dipolar SSH changes across 8°N (Figure 8a), it is of interest to relate I50d to the SSH anomaly signals in the tropical western Pacific Ocean. Your email address will not be published. Using the ocean state estimate of 1993–2016 from the Estimating the Circulation and Climate of the Ocean, Phase II, we detected strong interannual modulations in the shedding of cyclonic eddies at the Celebes Sea entrance. 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 fact that the ECCO2 state estimate is able to successfully simulate the leading two EOF mode signals observed in the tropical western Pacific Ocean is important because these large‐scale low‐frequency circulation changes are dynamically responsible for the interannual modulations in the surrounding marginal sea circulation, including that in the CS of our interest. Felt Report - Tell Us! 1. Frequency spectrum of sea surface height variance averaged in the box of 1°N–6°N, 117°E–125°E inside the Celebes Sea. Although the 50‐day oscillation is a localized phenomenon inside the CS, its interannual modulation can be expected to be controlled by broadscale conditions in the tropical western Pacific Ocean. 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. Please refer to the location map of the incidents in the Alert. The Philippines is surrounded by the Pacific Ocean, specifically the South China Sea, the Sulu Sea, the Celebes Sea, and the Philippine Sea.

Planets, Magnetospheric The Celebes Sea is unlike anywhere else on the planet. Geostatistics. 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 1918 Celebes Sea earthquake occurred on 15 August at 12:18 UTC near the Moro Gulf coast of Mindanao. In comparison to the CS case, the change in r value in the Makassar Strait case by adding the ENSO‐induced variability is more substantial: While |r| = 0.65 between S′(t) and Where is Celebes Sea? Figure 15a compares S′(t) and the best‐fit 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. In the Sibutu passage alone, an average of 14,000 ships passes yearly. To assess the impact of the 40‐ to 60‐day eddy variability upon the salinity signals inside the CS and its downstream Makassar Strait, we plot in Figure 12b the time‐varying salinity signals regressed to the I50d time series. The epicenter was approximately 400 km (249 miles) north-northeast of Manado, North Sulawesi Province, Indonesia. The ECCO2 simulation is based on the three‐dimensional hydrostatic and Boussinesq global ocean model of the Massachusetts Institute of Technology general circulation model (Marshall et al., 1997).

What cities are in Hinsdale County Colorado, Where is Grand County Colorado? While the broadbanded intraseasonal signals are detected in all subregions of the Indonesian Seas, the SST variability inside the CS was found to have a relatively narrow spectral peak centered at 56 days, whose characteristics are different from those in the Banda and Timor Seas. The tremor occurred at a depth of around 97 km (60 miles). , the correlation between S′(t) and Notice that the ERA‐interim wind stress data were used as an external forcing for the ECCO2 state estimate. Please check your email for instructions on resetting your password. According to this definition, high I50d, or active 40‐ to 60‐day oscillation, years are seen in 1993, 2002–2003, 2006–2010, and 2012–2015. In the regressed SSH field, Figure 8a reveals a dipolar meridional pattern quite similar to that of the EOF mode 2 (recall Figure 3c), with the dipole boundary aligned roughly along 8°N. Using the optimized parameters (e.g., initial temperature‐salinity conditions, background eddy diffusivity and viscosity, surface boundary conditions, and bottom drags) based on a Green's function approach (Menemenlis et al., 2005), the ECCO2 model is run unconstrained as in prognostic model simulations. Finally, the unique geometry of the CS basin, being approximately rectangular in shape, can work to amplify oceanic variability through resonance (Masumoto et al., 2001; Qiu et al., 1999). At present, the processes by which the 40‐ to 60‐day eddies interact with the CS western boundary and transform within the narrowed Makassar Strait are not well understood. However, it is encouraging to see that the ECCO2 state estimate is capable to simulate the EOF mode 2 of the AVISO SSH signals equally well, both in terms of their spatial patterns (Figures 3a and 3c) and their PC time series (Figures 3b and 3d).
