SITU DENSITY [6 records]

Record 1 2014-06-10

English

Subject field(s)
  • Petrography
  • Plastic Materials
  • Environment
CONT

The burial potential of plastic debris is chiefly dependent on the material' s density and abundance, in addition to the depositional environment. Here, we report the appearance of a new “stone” formed through intermingling of melted plastic, beach sediment, basaltic lava fragments, and organic debris from Kamilo Beach on the island of Hawaii. The material, herein referred to as “plastiglomerate, ” is divided into in situ and clastic types that were distributed over all areas of the beach.

CONT

Surnommé «plastiglomérat» [...], le matériau semi-naturel se compose d'une agrégation de roche volcanique, de sable, de débris de coquillage, de coraux et bien sûr, de matière plastique.

English

Subject field(s)
  • Environmental Studies and Analyses
CONT

The physical environment at the disposal site(depth, currents, waves, tides, weather conditions, salinity of receiving environment and presence of thermal stratification or density gradient, in situ sediment characteristics, topography and so forth) also affects the behaviour of dredged material during open-water disposal.

French

Domaine(s)
  • Études et analyses environnementales
CONT

L'environnement physique au site de dépôt incluant la profondeur, les courants, les vagues, les marées et les conditions météorologiques, la salinité du milieu récepteur, la présence d'une stratification thermique ou d'un gradient de densité, les caractéristiques des sédiments et la topographie ont aussi une incidence sur le comportement des matériaux dragués faisant l'objet d'un rejet en eaux libres.

Subject field(s)
  • Space Exploration Equipment and Tools
  • Spacecraft
CONT

The SEM subsystem consists of four instruments used for in situ measurements and monitoring of the near-earth(geostationary altitude) space environment and for observing the solar X-ray output. An energetic particles sensor(EPS) and high energy proton and alpha detector(HEPAD) monitor the incident flux density of protons, alpha particles, and electrons over an extensive range of energy levels. Solar output is monitored by an X-ray sensor(XRS) mounted on an X-ray positioning platform, fixed on the solar array yoke. Two redundant three-axis magnetometers, mounted on a deployed 3-meter boom, operate one at a time to monitor Earth's geomagnetic field strength in the vicinity of the spacecraft. The SEM instruments are capable of ground command-selectable, in-flight calibration for monitoring on-orbit performance and ensuring proper operation.

CONT

The Space Environment Monitor (SEM) measures in situ the effect of the Sun on the near-earth solar-terrestrial electromagnetic environment, providing real-time data to the Space Environment Services Center (SESC). The SESC, as the nation’s "space weather" service, receives, monitors, and interprets a wide variety of solar-terrestrial data, and issues reports, alerts and forecasts for special events such as solar flares or geomagnetic storms. This information is important to the operation of military and civilian radio wave and satellite communication and navigation systems, as well as electric power networks, and to the mission of geophysical explorers, Shuttle and Space Station astronauts, high-altitude aviators, and scientific researchers.

We have combined the ESR measurements with ionosonde data to establish a calibration and subsequently combined the ground-based and in situ determined profiles to give a composite positive ion density profile from the mesosphere to the thermosphere.
