Beskrivelse til det vorende Situations-Kaart over den vestlige kyst af Grønland.

Description

Danish naval officer Wilhelm August Graah (1793–1863) occupies a particular place in the history of Arctic exploration. During the 1820s, in an era when much of Greenland’s coast remained poorly charted, Graah led two crucial survey expeditions to map the inhospitable coastline of the enormous Arctic island.

His role as a surveyor and cartographer in the first expedition (1823-24) was part of his regular duties as a naval officer. The aim was to survey a number of inlets, harbors, and other locations in West Greenland, which at the time was the island’s economic hub (primarily international whaling). The overarching goal of the survey was to build an empirically anchored pilot chart (Situations-Kaart), and Graah’s published report (1825) was an essential step in that direction. The skill, determination, and clarity with which Graah fulfilled this assignment made him an ideal candidate to lead a far more trying and critical mapping mission a few years later.

The West Greenland Survey and ensuing publication

Graah’s cartographic and navigational report on Greenland’s southwest coast was meant to remedy the dubiously uncertain charts that were being used by ships at the time. In 1825, Graah published Beskrivelse til det voxende Situations-Kaart over den vestlige kyst af Grønland, a concise explanatory memoir that accompanied a set of folding charts and plates covering roughly 68°30′ to 73° N and providing accurate positions of headlands and harbours, as determined by astronomical observations. Graah had personally made these observations in his capacity as a naval officer.

Graah’s 1825 publication is technical in both purpose and tone. This was because the primary and explicit objective of these surveys was to correct and replace earlier inaccurate maps of West Greenland. The book opens with a publisher’s note in which Lieutenant Graah is commended for his earlier survey work in Iceland and West Greenland, noting that his efforts already contributed to new coastal charts for the Atlantic. The actual Introduction offers practical navigation advice for voyages to and from Greenland. Mariners are cautioned against sailing between Scotland and the Orkneys without a pilot, and warned of dangerous onshore winds near western Scotland when returning south.

This is followed by a section on ice conditions (isforhold), which distinguishes between field ice (fieldiis) and floe ice (flakiis), and vividly describes their varied and majestic formations. The text combines poetic imagery with practical guidance by comparing the ice to castles, churches, ships, and landscapes. The key takeaway, however, is recognizing hazardous ice formations and navigating safely under varying light and weather conditions.

Further sections discuss thermometers, currents, fog, wind, and weather conditions. Sailors are advised to monitor drops in water temperature as an indicator of nearby ice and to use reliable thermometers (notably those by Italian instrument-maker Antonio Cetti of Copenhagen). Information on the currents is limited, but the effects of fog and ice on local sailing conditions are discussed. The Northern Lights, or Aurora Borealis, are described as indicators of wind direction and approaching storms.

Under the section on compasses and magnetism, Graah notes that thunderstorms are rare and goes on to provide detailed observations on compass variation and deviation, cautioning against relying on low-sun readings and warning about the “dry compass,” whose paper rose could swell with moisture and stick to its pivot. On the construction or compilation of the sea chart, Graah underlines the reliability of his charts by explaining that they are based on positional determinations of fixed points anchored in 48 lunar distance observations. Both the coordinates and longitudes, as measured from Greenwich, are listed on page 13 and marked by rectangles on the accompanying charts. Under sailing directions, Graah describes the coasts, islands, skerries, harbours, and anchorages of the Davis Strait and Northern Greenland, with some of the information drawn from the report of Ross’ 1818 Northwest Passage expedition.

The explanatory text is accompanied by eight maps (on four sheets) and two coastal elevation profiles. At the time, the profiles were as crucial for navigation as the charts were, since the safest approach to the rugged Greenlandic coast often relied on visual identification of recognizable coastal features. Interestingly, the charts have intentionally misleading compass roses, with true north indicated by a separate arrow labelled S.N. (Sand Nord). The charts also lack latitude and longitude lines and contain only a limited number of depth soundings. These omissions were not because Graah did not know or wish to include them. Instead, the maps were meant to be used in combination with the text and profiles, reflecting the report’s nature as a key component in the compilation of a reliable situations-kaart (pilot chart) for Greenland’s rugged, ice-ridden coastline.

The nature of Graah’s legacy

Graah’s writings and charts amount to an overarching achievement: the conversion of vast, poorly understood Arctic coastlines into a functional cartographic resource. His work fused disciplined surveying practice with sustained on-site observation so that narrative, place-name, and chart come to reinforce one another. The result was not only better maps but a repeatable approach to Arctic coastal description that made Greenland’s shores legible to both seamen and scholars. They are, in essence, a synthesis of naval competence and exploratory curiosity. That synthesis is the source of Graah’s lasting legacy. His publications provided the conceptual and practical scaffolding upon which later explorers and scholars built. Moreover, he humanized the indigenous inhabitants by making them a key part of his explorations.

Historically, Graah’s work marks a pivotal moment in the history of Arctic mapping: the slow shift from fragmentary, impressionistic reports to the disciplined, reproducible cartography that not only made further exploration possible, but also safer and more systematic.
