Pharmaceuticals and personal care products measured in passive samplers at seven coastal sites off West Maui during February and March 2017 Pharmaceuticals and personal care products measured in passive samplers at seven coastal sites off West Maui during February and March 2017
Passive membrane samplers—semipermeable membrane devices and polar organic chemical integrative samplers—were deployed for 22 continuous days at 7 sites along the West Maui, Hawai'i, coastline in February and March 2017 to assess organic contaminants at shallow coral reef ecosystems from diverse upstream inputs.
Phenology effects in the North American Breeding Bird Survey Phenology effects in the North American Breeding Bird Survey
This data product provides summary information, by species, of changes in relative visibility of birds (phenology effects) through the April - July time period in which the North American Breeding Bird Survey (BBS) is conducted. Data are presented for 408 species of birds. Seasonal phenology effects are presented for selected latitudes and years, documenting changes in visibility and a...
Photo-documented sequences from 01 Jun 2021 - 30 Aug 2021 showing novel interactions between intraguild predators in southern Florida, USA, bobcat and Burmese python Photo-documented sequences from 01 Jun 2021 - 30 Aug 2021 showing novel interactions between intraguild predators in southern Florida, USA, bobcat and Burmese python
Entire photo-documented sequence from 01 June 2021-09 September 2021, including novel interactions between intraguild predators in southern Florida - the native bobcat (Lynx rufus) and the invasive Burmese python (Python bivittatus). A bobcat depredated an unguarded Burmese python nest and subsequently the python exhibited nest defense behavior following the return of both animals to the...
Photogrammetrically Controlled, Equirectangular Galileo Image Mosaics of Europa Photogrammetrically Controlled, Equirectangular Galileo Image Mosaics of Europa
The Solid State Imager (SSI) on NASA's Galileo spacecraft acquired more than 500 images of Jupiter's moon, Europa, providing the only moderate- to high-resolution images of the moon's surface. Images were acquired as observation sequences during each orbit that targeted the moon. Each of these observation sequences consists of between 1 and 19 images acquired close in time, that...
Photosynthetically Active Radiation Measurements Collected at Malheur Lake, OR, 2017-2018 Photosynthetically Active Radiation Measurements Collected at Malheur Lake, OR, 2017-2018
The USGS measured photosynthetically active radiation (PAR, wavelength between 400 and 700 nanometers) at Malheur Lake, Oregon, as vertical profiles and as continuous measurements at a fixed depth, in 2017 and 2018. Malheur Lake is a large, shallow, turbid lake located in southeastern Oregon that fluctuates widely in surface area in response to yearly precipitation and climatic cycles...
