We implemented our planning algorithm with a team of drones to conduct multiple photographic aerial wildlife surveys of Cape Crozier, one of the largest Ad\u00e9lie penguin colonies in the world containing more than 300,000 nesting pairs. We used the same technique at the two smaller Ad\u00e9lie penguin colonies on Ross Island (Cape Bird and Cape Royds). At Cape Crozier, over 2 square kilometers was surveyed in about 3 hours. In contrast, previous human-piloted single-drone surveys of the same colony required over 2 days to complete. The resulting data are geo-referenced, 3d images of penguin colonies created from the UAV imagery. Raw images were stitched together using Metashape (https://www.agisoft.com/).", "east": 170.0, "geometry": ["POINT(167.5 -77.5)"], "keywords": "Aerial Imagery; Aerial Survey; Antarctica; Biota; Geotiff; Penguin; Photo/video; Photo/Video; Population Count; Ross Island; UAV", "locations": "Antarctica; Ross Island", "north": -77.0, "nsf_funding_programs": "Antarctic Organisms and Ecosystems", "persons": "Ballard, Grant; Schmidt, Annie; Shah, Kunal", "project_titles": "Does Nest Density Matter?

The mooring was situated at the seawater terminus of the McMurdo Station seawater intake jetty at 21 m deep, typically under thick sea ice cover. The automated 360\u00b0 pan-tilt-zoom (ptz) camera, inside of an air-filled self-cleaning dome, was programmed to move to 42 ptz \"waypoints\" every hour and take a still 1920x1080 JPG image for archiving. Lights, oriented in one direction only, illuminated a rock/rubble slope for much of each winter, when there was no natural illumination. The camera was situated on a concrete block, which elevated the camera about 1m off of the seabed. Motile and sessile benthic biota, including notothenioid fishes, anemones, pycnogonids, asteroids, soft-corals, sponges, and nudibranchs are commonly seen in the images. Some ptz waypoints survey the water column and underside of the sea ice, capturing also the presence of larval/juvenile fishes and other plankton/nekton in the water column. Maximum intervals between subsequent images from the same ptz waypoint were about 1 hour, though many waypoints were captured at somewhat higher frequency. Interval images, taken at 5-min intervals irrespective of camera orientation, were also captured. Images are occasionally obscured/impacted by the camera dome\u0027s wiper, darkness, low visibility, minor fouling of the camera dome, and out-of-focus lens elements.

The effects of these environmental changes are poorly understood, but preliminary data suggest that they are driving a biological invasion. Specifically, large populations of skeleton-crushing king crabs, Paralomis birsteini, have been detected off Marguerite Bay on the West Antarctic Peninsula. These crabs appear to be invading the continental shelf region where benthic communities have evolved in the absence of such top-predators. Thus, this invasion could result in a wholesale restructuring of the Antarctic benthic ecosystem. The proposed work seeks to document this invasion and better understand the effects of the introduction of P. birsteini on the ecology of this region. A towed underwater vehicle will be used to photographically image communities, and communities with and without P. birsteini will be compared quantitatively. Additionally, crabs will trapped and various aspects of their morphology and physiology will be assessed. This research is unique in that it will document a biological invasion in real-time and it will therefore enhance our general understandings of the drivers of invasion and resilience in biological communities. Results will be widely disseminated through publications as well as through presentations at national and international meetings. In addition, raw data will be made available through open-access databases.

Erebus is one of only a handful of volcanoes worldwide that have lava lakes with readily observable and nearly continuous Strombolian explosive activity. Erebus is also unique in having a permanent convecting lava lake of anorthoclase phonolite magma. Over the years significant infrastructure has been established at the summit of Mt. Erebus as part of the Mount Erebus Volcano Observatory (MEVO), which serves as a natural laboratory to study a wide range of volcanic processes, especially magma degassing associated with an open convecting magma conduit. The PI proposes to continue operating MEVO for a further five years. The fundamental fundamental research objectives are: to understand diffuse flank degassing by using distributed temperature sensing and gas measurements in ice caves, to understand conduit processes, and to examine the environmental impact of volcanic emissions from Erebus on atmospheric and cryospheric environments. To examine conduit processes the PI will make simultaneous observations with video records, thermal imaging, measurements of gas emission rates and gas compositions, seismic, and infrasound data.\n An important aspect of Erebus research is the education and training of students. Both graduate and undergraduate students will have the opportunity to work on MEVO data and deploy to the field site. In addition, this proposal will support a middle or high school science teacher for two field seasons.

It has a unique geochemistry among the Earth\u0027s active volcanoes and is also unique in hosting a persistent convecting lake(s) of anorthclase phonolite magma in its summit crater.

Erebus Volcano Observatory (MEVO III) improving our current understanding of the Erebus eruptive and non-eruptive magmatic system using an integrated approach from geophysical, geochemical and remote sensing observations. This goal can be grouped into the following fundamental research objectives: (a) to sustain year-round surveillance of on-going volcanic activity primarily using geophysical observatories; (b) to understand processes within the convecting conduit which feeds the persistent lava lakes; and (c) to understand the impact of Erebus eruptive activity upon the Antarctic environment.

The effects of these environmental changes are poorly understood, but preliminary data suggest that they are driving a biological invasion. Specifically, large populations of skeleton-crushing king crabs, Paralomis birsteini, have been detected off Marguerite Bay on the West Antarctic Peninsula. These crabs appear to be invading the continental shelf region where benthic communities have evolved in the absence of such top-predators. Thus, this invasion could result in a wholesale restructuring of the Antarctic benthic ecosystem. The proposed work seeks to document this invasion and better understand the effects of the introduction of P. birsteini on the ecology of this region. A towed underwater vehicle will be used to photographically image communities, and communities with and without P. birsteini will be compared quantitatively. Additionally, crabs will trapped and various aspects of their morphology and physiology will be assessed. This research is unique in that it will document a biological invasion in real-time and it will therefore enhance our general understandings of the drivers of invasion and resilience in biological communities. Results will be widely disseminated through publications as well as through presentations at national and international meetings.

It has been shown from measurements from space by the IMAGE spacecraft that the dayside hydrogen emission is directly related to dayside reconnection processes. A four channel all-sky images had been operating at South Pole during 2004-2007 to observe auroral features in specific wavelengths channels that allowed a quantitative investigation of proton aurora. This was accomplished by measuring the Hydrogen Balmer beta line at 486.1 nm and by monitoring another wavelength band for subtracting non proton produced background emissions. South Pole allows these measurements because of the 24 hour darkness and favorable conditions even on the dayside. To increase the scientific return it was also attempted to measure the Doppler shift of the hydrogen emissions because that provides diagnostics regarding the energy of the protons. Thus the proton camera measured 3 wavelength bands simultaneously in the vicinity of the Balmer beta line to provide the line intensity near zero Doppler shift, at a substantial Doppler shift and a third channel for background. \n\nThe 4-channel all-sky camera at South Pole was modified in 2008 in order to observe several types of auroras, and to distinguish the cusp reconnection aurora from the normal plasma sheet precipitation. The camera simultaneously operates in four wavelength regions that allow a distinction between auroras that are created by higher energy electrons (greater than 1 keV) and those created by low energy (less than 500 eV) precipitation. The cusp is the location where plasma enters the magnetosphere through the process of magnetic reconnection. This reconnection occurs where the Interplanetary Magnetic Field (IMF) and the terrestrial magnetic field are oriented in opposite directions. \n\nThe data are represented as keograms (geomagnetic north-south slices through the time series of images) for the four different wavelengths.
