Sensors, 2011 Wireless Sensor Networks promised to do for observation systems what consumer electronics have done for areas like photography—drive down the price per observation (photograph), introduce new functionality and capabilities, and make, what had been a ...

Perspectives on a Global Observing System to Assess Ocean Health
Frontiers in Marine Science, 2018 Concern over the deterioration of the oceans has generated a demand for a system able to assess ocean health globally, and approaches to assess ocean health globally and an observing system delivering the data to support this assessment are now being ...

Scaling Up From Regional Case Studies to a Global Harmful Algal Bloom Observing System
Frontiers in Marine Science, 2019 Harmful algal blooms (HABs) produce local impacts in nearly all freshwater and marine systems. They are a problem that occurs globally requiring an integrated and coordinated scientific understanding, leading to regional responses and solutions.

Frontiers in Earth Science, 2022 Glaciers have melted rapidly in the Yarlung Zangbo River Basin due to recent climate change, which has accelerated the expansion of glacial lakes. We performed a systematic survey of glacial lakes in the Yarlung Zangbo River Basin using the Google Earth ...

Electronic Notes in Theoretical Computer Science, 2000 AbstractThe notion of observation plays a central role in current theories of concurrency. In this paper we investigate observation from the point of view of observation structures and observations systems; the former represent the observable entities, the later specify the allowed observations and their outcome.

Observability of nonlinear systems [PDF]
Mathematica Bohemica, 2006 Summary: Observability of a general nonlinear system -- given in terms of an ODE \(\dot {x}=f(x)\) and an output map \(y=c(x)\) -- is defined as in linear system theory (i.e.\,if \(f(x)=Ax\) and \(c(x)=Cx\)). In contrast to standard treatment of the subject we present a criterion for observability which is not a generalization of a known linear test ...

Drift-aware sea ice thickness maps from satellite remote sensing [PDF]
The CryosphereThe standard approach to deriving gridded sea ice thickness (SIT) from satellite altimeters is to aggregate the original along-track SIT estimates over a 1-month period to achieve sufficient coverage across the Arctic.

Ocean and Coastal Acidification off New England and Nova Scotia [PDF]
Oceanography, 2015 New England coastal and adjacent Nova Scotia shelf waters have a reduced buffering capacity because of significant freshwater input, making the region’s waters potentially more vulnerable to coastal acidification. Nutrient loading and heavy precipitation
