New York, April 1990: A Photographic Record

Aquestes fotografies de Nova York i de Boston, totes en blanc i negre, es van fer en abril del 1990, amb una cambra rèflex Asahi Pentax Spotmatic II amb objectiu de 50 mm, tot fent servir negatius Kodak Safety Film 5063. El Museu de la Universitat d’Alacant en conserva una col·lecció completa; vuitanta-set còpies fotogràfiques de 32 x 24 cm amb tintes Ultrachrome sobre paper Ilford Gold Fibre Silk de 310 gr/m² realitzades al “Estudio Paco Mora” de València l’any 2015, amb digitalització prèvia a partir dels negatius originals mitjançant un escàner Haselblad Flextight X 1 a una resolució de 3.200 punts per polzada.

Photographic prints of the elevations and floor plans of Harvard College or "Old College" used for publication by Samuel E. Morison, February 1933

Contains seven photographic prints elevations and floor plans of Harvard College used in an article on "Old College" by Samuel E. Morison. Includes first, second, and third floor plans; north, south, and east elevations; and one overhead perspective of the structure.

Engravings of a plan and an exterior view of Harvard Hall drawn by Pierre Eugène du Simitière, (photographic prints, photostats, and negative photostats), [ca. 1764]

The floor plan details all three floors of Harvard Hall, including its cellars, kitchen, chapel, and library. The items in this folder were reproduced from "The Burning of Harvard Hall, 1764, and its consequences," presented by F. Apthorp Foster at the April 1911 meeting of the Colonial Society of Massachusetts, and published in the Publications of the Colonial Society of Massachusetts, Volume XIV. The floor plan and exterior views were created by Pierre Eugène du Simitière in circa 1764. The original drawings are held in the Pierre Eugène du Simitière collection in the Ridgeway Branch of the Library Company of Philadelphia.

Data and Code archive for the interpolation of surface ocean carbon dioxide

We have developed a statistical gap-filling method adapted to the specific coverage and properties of observed fugacity of surface ocean CO2 (fCO2). We have used this method to interpolate the Surface Ocean CO2 Atlas (SOCAT) v2 database on a 2.5°×2.5° global grid (south of 70°N) for 1985-2011 at monthly resolution. The method combines a spatial interpolation based on a 'radius of influence' to determine nearby similar fCO2 values with temporal harmonic and cubic spline curve-fitting, and also fits long term trends and seasonal cycles. Interannual variability is established using deviations of observations from the fitted trends and seasonal cycles. An uncertainty is computed for all interpolated values based on the spatial and temporal range of the interpolation. Tests of the method using model data show that it performs as well as or better than previous regional interpolation methods, but in addition it provides a near-global and interannual coverage.
