Spectral Variability Of Oil Slicks Under Different Observing Conditions Derived From Satellite And Airborne Optical Remote Sensing, Chuanmin Hu
C-IMAGE data
In this dataset, we present the spectral variability of oil slicks under different observing conditions using MODIS (Moderate Resolution Imaging Spectroradiometer), MERIS (Medium Resolution Imaging Spectrometer), MISR (Multi-angle Imaging SpectroRadiometer), Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and AVIRIS (Airborne Visible/ Infrared Imaging Spectrometer). Optical remote sensing is commonly used to detect oil in the surface ocean due to the spectral differences between oil and water, allowing to modulate oil–water spatial and spectral contrasts. However, understanding these contrasts is challenging because of variable results from laboratory and field experiments, as well as different observing conditions and spatial/spectral resolutions of remote …
Remote Sensing Estimation Of Surface Oil Volume During The 2010 Deepwater Horizon Oil Blowout In The Gulf Of Mexico: Scaling Up Aviris Observation With Modis Measurements, Chuanmin Hu, Lian Feng
Remote Sensing Estimation Of Surface Oil Volume During The 2010 Deepwater Horizon Oil Blowout In The Gulf Of Mexico: Scaling Up Aviris Observation With Modis Measurements, Chuanmin Hu, Lian Feng
C-IMAGE data
This dataset contains Rayleigh corrected reflectance data from 19 MODIS images collected between April and July 2010, along with their corresponding maps of surface oil volume, maps of relative oil thickness of different classes, and maps of probability distributions of different thicknesses. Surface oil was estimated by spatially scaling up AVIRIS observations to synoptic MODIS measurements, which were the used to derived oil classification and probability maps.

C-IMAGE data
This dataset includes Moderate Resolution Imaging Spectroradiometer (MODIS), Airborne Visible-InfraRed Imaging Spectrometer (AVIRIS), Landsat and Hyperspectral Imager for the Coastal Ocean (HICO) images used in the paper: Hu, C., Feng, L., Hardy, R. F., & Hochberg, E. J. (2015). Spectral and spatial requirements of remote measurements of pelagic Sargassum macroalgae. Remote Sensing of Environment, 167, 229–246. doi:10.1016/j.rse.2015.05.022, together with the delineated sargassum features. The in situ spectral measurements used as endmembers to simulate the results are also included.

Refinement Of The Critical Angle Calculation For The Contrast Reversal Of Oil Slicks Under Sunglint, Yingcheng Lu, Shaojie Sun, Minwei Zhang, Brock Murch, Chuanmin Hu
Refinement Of The Critical Angle Calculation For The Contrast Reversal Of Oil Slicks Under Sunglint, Yingcheng Lu, Shaojie Sun, Minwei Zhang, Brock Murch, Chuanmin Hu
C-IMAGE Publications
It has long been observed that oil slicks under sunglint can reverse their optical contrast against nearby oil‐free seawater. Such a phenomenon has been described through both empirical statistical analysis of the sunglint strength and modeled theoretically using a critical angle concept. The critical angle, in this model, is the angle at which the image pixels show no or negligible contrast between oiled and nonoiled seawater. Pixels away from this critical angle show either positive or negative contrast from the oil‐free pixels. Although this concept has been fully demonstrated in the published literature, its calculation needs to be further refined …
Sun Glint Requirement For The Remote Detection Of Surface Oil Films, Shaojie Sun, Chuanmin Hu
Sun Glint Requirement For The Remote Detection Of Surface Oil Films, Shaojie Sun, Chuanmin Hu
C-IMAGE Publications
Natural oil slicks in the western Gulf of Mexico are used to determine the sun glint threshold required for optical remote sensing of oil films. The threshold is determined using the same‐day image pairs collected by Moderate Resolution Imaging Spectroradiometer (MODIS) Terra (MODIST), MODIS Aqua (MODISA), and Visible Infrared Imaging Radiometer Suite (VIIRS) (N = 2297 images) over the same oil slick locations where at least one of the sensors captures the oil slicks. For each sensor, statistics of sun glint strengths, represented by the normalized glint reflectance (L GN, sr−1), when oil slicks can and cannot be …
Moderate Resolution Imaging Spectroradiometer (Modis) Observations Of Cyanobacteria Blooms In Taihu Lake, China, Chuanmin Hu, Zhongping Lee, Ronghua Ma, Kun Yu, Daqiu Li, Shaoling Shang
Moderate Resolution Imaging Spectroradiometer (Modis) Observations Of Cyanobacteria Blooms In Taihu Lake, China, Chuanmin Hu, Zhongping Lee, Ronghua Ma, Kun Yu, Daqiu Li, Shaoling Shang
Marine Science Faculty Publications
A novel approach was used with data from the Moderate Resolution Imaging Spectroradiometer (MODIS) to characterize the intense blooms of cyanobacteria (primarily Microcystis aeruginosa) in Taihu Lake, China's third largest freshwater lake. The approach involves first deriving a floating algae index (FAI) based on the medium‐resolution (250 and 500 m) MODIS reflectance data at 645, 859, and 1240 nm after correction of the ozone/gaseous absorption and Rayleigh scattering effects and then objectively determining the FAI threshold value (−0.004) to separate the bloom and nonbloom waters. By definition, the term “bloom” or “floating algae” refers to bloom where cyanobacteria form …
