Interannual phenomena such as El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) also influence upwelling activity in this region. This study analyzed the relationship between upwelling intensity (UI_sst) and those variables and their impact on oceanographic features such as Sea Surface Temperature (SST) and chlorophyll-a concentration. We used satellite imagery data, including SST from the National Oceanic and Atmospheric Administration (NOAA) and chlorophyll-a from MODIS, to analyze the aforementioned issue. To identify the impact of wind patterns on coastal upwelling, we analyzed using zonal wind stress from ERA-5 Data. Quantification of UI_sst is defined as the SST gradient between the coastal and open ocean waters. Linear and partial correlation analysis between UI_sst with the Ocean Niño Index (ONI) and Dipole Mode Index (DMI) were conducted to see the influence of ENSO and IOD phenomena. Anomaly analysis was also conducted on SST, chlorophyll-a concentration, zonal windstress and UI_sst to see how large the values were during the years of the ENSO and IOD events. Upwelling in the SI region typically occurs during southeast monsoon (SEM) periods, starting earlier in the East side (Nusa Tenggara Islands) and moving towards the West side (South Coast of Java). The correlation analysis (both linear and partial) indicates that the IOD has a stronger influence on UI_sst in the SI region compared to ENSO, especially during June to October (SEM periods). This finding is confirmed by anomaly analysis, which reveals significant changes in SST, chlorophyll-a concentration, zonal windstress, and UI_sst during ENSO and IOD events. The magnitude of the anomalies is generally stronger during IOD events than those observed under ENSO conditions.</p></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"202 ","pages":"Article 102543"},"PeriodicalIF":2.1,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1385110124000765/pdfft?md5=68cb95fa1ef611cc84c343aaca6d9005&pid=1-s2.0-S1385110124000765-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, phytoplankton classification has heavily relied on chemical analysis methods based on phytoplankton pigments, such as High-Performance Liquid Chromatography (HPLC) analysis. This approach limits the classification resolution to the phylum level of phytoplankton, making it difficult to refine classification to the genus or species level. With the observation of the hyperspectral ocean satellite PACE (Plankton, Aerosol, Cloud, ocean Ecosystem mission) louched by NASA in February 2024, there is potential to achieve finer classification of phytoplankton based on differences in spectral characteristics. This study cultivates various phytoplankton species in the laboratory to observe their light absorption properties (e.g., specific absorption coefficients spectra under unit concentration), investigating the spectral differences between different phyla and among species within the Dinoflagellates and Diatoms. Based on the observed absorption and scattering properties of each phytoplankton species, we simulated the remote sensing reflectance of different species under various ocean color components, examining the potential of hyperspectral remote sensing discrimination of phytoplankton types, and analyzing the impact of Chlorophyll &lt;em&gt;a&lt;/em&gt; (Chla), colored dissolved organic matter (CDOM), and non-algal particles (NAP) concentrations on the remote sensing discrimination. The results show significant differences in absorption spectra between different groups of phytoplankton (i.e., Diatoms, Dinoflagellates, Xanthophytes, Coccolithophores, Chlorophytes, Cyanobacteria, Cryptophytes). Among species within the Dinoflagellate group, there are also significant spectral differences, while species within the Diatom group exhibit relatively small variations in their spectral shapes. As Chla concentration increases, the potential for remote sensing discrimination of phytoplankton species also increases; conversely, lower Chla concentrations pose greater challenges for remote sensing disscrimiantion. Other ocean color components, such as increased CDOM or NAP concentrations, interfere with the spectral characteristics of phytoplankton in the blue-green spectral domain. Using hierarchical clustering for phytoplankton classification, the results indicate that Cyanobacteria and Chlorophytes can be well distinguished from other group at lower NAP concentrations, while Diatoms, Cryptophytes, and Xanthophytes are not easily distinguishable from each other. Differentiating between species within the same group using remote sensing data presents significant challenges.

They occur below the sea surface and can be observed using optical and radar sensors due to their interactions with surface waves. Nonlinear internal waves, known as Internal Solitary Waves (ISW), maintain their coherence and visibility through nonlinear hydrodynamics and appear as long quasilinear stripes in images. Optical sensors can capture changes in sea surface roughness modulated by ISW when their location is close to specular reflection from the sun. Optical imagery with wide area coverage and high temporal resolution has the potential to track and analyze ISW dynamics. However, a comprehensive analysis of the mechanisms underlying ISW manifestation patterns in optical images is necessary. The GCOM-C/SGLI satellite, equipped with a visible-near infrared radiometer and an infrared scanner, provides a detailed view of ISW manifestations using various scanning techniques. By analyzing SGLI products that detect ISW patterns, this study investigated how these waves manifest on the sea surface. The comparison between Level-1B data and Level-2 Ocean products observed by the SGLI sensor reveals that ISW patterns significantly affect ocean color parameters and thermal channel data. The consistent ISW manifestation pattern detected in TOA radiance and ocean color products suggests that ISWs impact sea surface roughness. Additionally, the detection of ISW patterns in SST data is a notable finding, highlighting the potential influence of ISWs on air-sea interactions and the atmospheric boundary layer. Understanding these impacts is crucial for remote sensing applications, particularly for long-term internal wave monitoring and ensuring that smaller-scale internal wave signals do not interfere with large-scale satellite estimations of ocean color.</p></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"202 ","pages":"Article 102541"},"PeriodicalIF":2.1,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1385110124000741/pdfft?md5=741457f247ddbefce26f58d47b644ebf&pid=1-s2.0-S1385110124000741-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142161530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
