Multi-Year Observations of Fluorescence and Backscatter at the Southern Ocean Time Series (SOTS) Shed Light on Two Distinct Seasonal Bio-Optical Regimes [PDF]
Frontiers in Marine Science, 2019 This work presents insights from 6 years of chlorophyll-a (Chl) fluorescence and backscatter (700 nm) data at the Southern Ocean Time Series (SOTS) moorings, located in the Subantarctic Zone (SAZ) southwest of Tasmania.

The high-frequency backscattering angular response of gassy sediments: Model/data comparison from the Eel River Margin, California [PDF]
, 2002 A model for the high-frequency backscatter angular response of gassy sediments is proposed. For the interface backscatter contribution we adopted the model developed by Jackson et al. @J. Acoust. Soc. Am. 79, 1410–1422 ~1986!#, but added modifications to

Interannual variability in North American grassland biomass/productivity detected by SeaWinds scatterometer backscatter [PDF]
, 2005 We analyzed 2000–2004 growing-season SeaWinds Ku-band microwave backscatter and MODIS leaf area index (LAI) data over North America. Large anomalies in mid-growing-season mean backscatter and LAI, relative to 5-year mean values, occurred primarily in the

Backscatter Communications [PDF]
IEEE Journal of Microwaves, 2021 This paper addresses backscatter communications as a new paradigm for Internet of Things (IoT) sensor wireless solutions. The paper clearly presents the history background of the technology and then makes a summary of the more recent developments form several groups around the world, with emphasis in US and Europe groups.
