  • Central Mali oils soaps and soda-ash documentaries

    Work
    Creator: Heath, Jeffrey
    Description: Videos done in the course of linguistic fieldwork in Central Mali. They are presented here in two or three video formats. The videos show how Dogon villagers press oil from nuts and fruit pits, make liquid soda ash (French potasse), and make soap. Some are in standard documentary form, some early ones ("compendiums") are sequences of brief clips. Most were made in Beni village or in the Douentza area.
  • Central Mali hunting and collecting documentaries

    Work
    Creator: Heath, Jeffrey
    Description: These videos were shot in Dogon villages. They show how wild foods (insects and plants) are obtained and consumed. Most are presented here in three video formats.
  • Central Mali herding and dairy documentaries

    Work
    Creator: Heath, Jeffrey
    Description: These videos were produced in the course of linguistic fieldwork in central Mali. They are presented here in multiple video formats. The cattle herders par excellence in the zone are traditional Fulbe, who enter towns and Dogon villages to sell fresh and curdled milk along with butter.
  • Central Mali agriculture documentaries

    Work
    Creator: Heath, Jeffrey
    Description: Videos produced in the course of linguistic fieldwork. Most are presented here in three different video formats. "Gardening Diondiori" illustrates dry-season farming mostly of cash crops using ground water (springs, drying ponds and rivers, underground water sources). The other videos in this block are of ordinary rainwater agriculture done in the rainy season, featuring Dogon people and, in the case of "Rice harvest and threshing," Bangande (speakers of Bangime), who have the same agricultural methods. The principal rainy season crop in the zone is millet (Cenchrus spicatus), but most of the documentaries here are about secondary crops (cowpea, fonio, groundnut, peanut, groundnut, roselle, rice, sesame, sweet potato). "Driving off grain-eating birds" is based on an unsteady cellphone video brought to us, except for the final segments which we shot.
  • Central Mali food and drink preparation documentaries

    Work
    Creator: Heath, Jeffrey
    Description: These are documentaries made in the course of linguistic fieldwork in central Mali. Most are presented here in three different video formats. All of those in the present group are of Dogon people. Beni village near Douentza figures in many of them. "Cooked spiced millet with roselle leaves" and "steamed cowpeas with millet" are from Walo village. "Cream of millet with tamarind" is from Bendiely village. "Beer brewing" is from Yanda village. "Groundnuts roasted and boiled" is from near Sévaré. "Macari" is from Kowo village near Sévaré. See also the separate works "Central Mali agriculture documentaries" and "Central Mali herding and dairy documentaries".
  • Central Mali cultural event documentaries

    Work
    Creator: Heath, Jeffrey
    Description: Documentaries about festivals (some annual, some less often) and ceremonial events, filmed in the course of linguistic fieldwork in central Mali. Those relating to Dogon are: Bamba fishfest 2010; Degeju festival at Yendouma 2012; Dogon cowfest at Pergue 2011; Ginna Dogon 2011 Bandiagara; Koira Bery festival 2010; Songho circumcision 2010; Tomtoms of Tupere; and Yanda huntfest 2010. Bangande (speakers of Bangime) are represented in Tabaski at Bounou (the Muslim feast of the ram). Fulbe are represented in Cowfest at Bamguel 2011 (cowfests are a Fulbe specialty, but the Dogon of Pergue have their own). Songhay is represented by Coronation at Hombori 2011 (the enthronment or "intronisation" of a new king of Hombori). Videos are available in multiple formats.
  • Maximum Spreading Speed for Magnetopause Reconnection: Model Dataset

    Work
    Creator: Welling, Daniel and Walsh, Brian
    Description: The goal of this simulation was to examine the spread of magnetic reconnection across the dayside magnetopause upon the arrival of a tangential discontinuity of the interplanetary magnetic field from a purely northward to southward configuration. Simple solar wind conditions were used to give us input into the system. A very high resolution grid setup was used in BATS-R-US.
  • Data in support of the study "Modeled Response of Greenland Snowmelt to the Presence of Biomass Burning-Based Absorbing Aerosols in the Atmosphere and Snow"

    Work
    Creator: Ward, Jamie L., Flanner, Mark G., Bergin, Mike, Dibb, Jack E., Polashenski, Chris M., Soja, Amber J., Thomas, Jennie L.
    Description: Biomass burning produces smoke aerosols that are emitted into the atmosphere. Some smoke constituents, notably black carbon (BC), are highly effective light-absorbing aerosols (LAA). Emitted LAA can be transported to high albedo regions like the Greenland Ice Sheet (GrIS) and affect local snowmelt. In the summer, the effects of LAA in Greenland are uncertain. To explore how LAA affect GrIS snowmelt and surface energy flux in the summer, we conduct idealized global climate model simulations with perturbed aerosol amounts and properties in the GrIS snow and overlying atmosphere. The in-snow and atmospheric aerosol burdens we select range from background values measured on the GrIS to unrealistically high values. This helps us explore the linearity of snowmelt response and to achieve high signal-to-noise ratios. With LAA operating only in the atmosphere, we find no significant change in snowmelt due to the competing effects of surface dimming and tropospheric warming. Regardless of atmospheric LAA presence, in-snow BC-equivalent mixing ratios greater than ~60 ng/g produce statistically significant snowmelt increases over much of the GrIS. We find that net surface energy flux changes correspond well to snowmelt changes for all cases. The dominant component of surface energy flux change is solar energy flux, but sensible and longwave energy fluxes respond to temperature changes. Atmospheric LAA dampen the magnitude of solar radiation absorbed by in-snow LAA when both varieties are simulated. In general, the significant melt and surface energy flux changes we simulate occur with LAA quantities that have never been recorded in Greenland.
