Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2014S17, deployed during POLARSTERN cruise ANT-XXX/2 (PS89)

Snow height was measured by the Snow Depth Buoy 2014S17, an autonomous platform, drifting on Antarctic sea ice, deployed during POLARSTERN cruise ANT-XXX/2 (PS89). The resulting time series describes the evolution of snow depth as a function of place and time between 2014-12-20 and 2015-02-01 in sample intervals of 1 hour. The Snow Depth Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on first year ice. In addition to snow depth, geographic position (GPS), barometric pressure, air temperature, and ice surface temperature were measured. Negative values of snow depth occur if surface ablation continues into the sea ice. Thus, these measurements describe the position of the sea ice surface relative to the original snow-ice interface. Differences between single sensors indicate small-scale variability of the snow pack around the buoy. The data set has been processed, including the removal of obvious inconsistencies (missing values). In this data set, diurnal variations occur in the data set, although the sonic readings were compensated for temperature changes. Records without any snow depth may still be used for sea ice drift analyses.

First Floor, Old Harvard Hall 1667-1764, 1935

Floor plan of the first floor of Old Harvard Hall drawn by H.R. Shurtleff in 1935. Includes the hall, kitchen, buttery, and two chambers

First Floor, Stoughton, 1874

Floor plan of renovations for the first floor of Stoughton Hall, as drawn by William Rotch Ware in 1874. Includes dimensions for student chambers, hallways, and coal furnaces.

Front elevation and floor plans for first and second floors, ink and wash on paper, [ca. 1812]

Drawing by Charles Bulfinch of proposed plans for University Hall which were later rejected. Includes sketches of the front exterior view of the University Hall, and separate floor plans for the ground and second floors. Bulfinch designed a ground floor with a chapel and four dining halls each holding 100 students, a second floor with a gallery in the chapel and three rooms over the dining halls for public examinations and meetings of the Corporation and Overseers; and a basement under the halls intended for a kitchen under the dining halls and recitation rooms under the chapel.

[Salary of the minister of the first parish of Cambridge for 1792], undated

Small scrap of paper with a handwritten calculation of the January 1792 salary of an unidentified minister, presumably the minister of the first Parish of Cambridge based on lines for "Parsonage" and "Lexington farm fund."

First Draught of substitute, [1799 February]

One folio-sized leaf containing a handwritten draft of the substitute clause providing Cambridge a year to provide evidence that Harvard exceeded £500 in real estate income. The clause was included in the annual tax act, approved on February 28, 1799 (Chapter 75).

Notebook containing Nathan Prince's defense against the first articles of accusation against him, Nov. 26, 1741

A penciled notation on this notebook's cover indicates that the handwriting is of Thomas Prince, Nathan's brother. Informally titled "An Heavenly Interposition of a Storm & Tempest," this notebook details Prince's point-by-point responses to the accusations against him. Prince also includes lists of each accusation and those making the accusation; he appears to have believed there was a conspiracy against him.
