description: Generic Epicycle: The manuscript diagrams for the generic epicycle follow generally the description of Calcidius's text. The most common divergence from the text's description is a failure of the radii tangent to the epicycle to be, in fact, tangent. Calcidius's account here might not be clear to a reader not already familiar with such a diagram. The purpose of the diagram is to identify the forward and retrograde arcs of the epicycle as well as the stationary points of the planet on the epicycle. The zodiacal circle and the earth at its center are specified first. The epicyclic circle EZH is then presented, but the text requires a preexisting diagram and simply discusses the motion of points on the diagram. The three points labeling the epicycle only become clear as the description proceeds, the points Z and H being the points of tangency with the two radii drawn to the zodiacal circle and the point E being between the zodiacal point A and the center M of the epicycle along a radius from the earth through M to A. Once this figure is recognized, the reader can follow Calcidius's account of epicyclic motion, which he applies here to any planet and gives no specifics of planetary motion. The epicycle here is fixed and does not move around the zodiac. The epicycle only rotates, with its motion in the same sense as the celestial sphere, from east to west, showing the motion of a planet on its periphery. Calcidius point out the two locations, or regions, of planetary station in two very small arcs including the tangent points H and Z. He then labels the passage from Z through E to H as the proper motion of the planet on the periphery of the epicycle and the passage from H to Z as the retrograde motion of the planet. He continually reminds the reader that the planetary motions are seen against the background of the zodiac rather than directly on the epicyclic circle.

description: Bounded Elongation of Venus Desciptive: The manuscript diagrams for this text and for that following it, the epicyclic explanation of Venus's elongation, are among the most corrupted in all of the Calcidian corpus. The positions of X and K vary extensively, and there are usually two concentric circles within the zodiacal circle, neither of which is called for by the text. However, most scribes either chose not to correct these variants in their exemplars or else did not recognize any error in such variant diagrams. From the eleventh century onward, some scholars did recognize and correct them. The text calls for a severely descriptive, not explanatory, image. The zodiacal circle, a central earth at X, a radius passing through the Sun's center K to the point B, and two radii to two zodiacal points A and Γ, located respectively 50° to the east and to the west of B, are sufficient to complete the diagram. With the Sun always seen along XKB, the planet Venus never appears farther away from it than the two limiting radii XA and XΓ at angles of 50° from XKB.

description: Solar Epicycle: An epicycle is a circle whose center is fixed on and revolves around the periphery of another circle at a uniform speed. The epicycle itself will rotate at its own uniform speed. Manuscript diagrams for this topic are recognizably related to each other, but the details of the epicyclic circles vary and suggest some difficulty in the understanding by early medieval scholars of these combinations of circular motions. Calcidius states that the motions of the circles are uniform, although his description omits some potentially useful elements, such as the division of the epicycle into four equal quadrants; he does this explicitly only for the deferent circle. His definition of an epicycle is extremely general. The geometrical framework is simple. The same zodiacal circle ABΓΔ, ordered anti-clockwise, as used in the explanation by an eccentric circle appears again here. The earth is at the center Θ. Concentric with the zodiacal circle is the deferent circle MONΞ (anti-clockwise). The epicyclic circle has its center initially at M. The periphery of the epicycle is labelled anti-clockwise EZHK. The rotation of each of these three circles is specified. ABΓΔ rotates daily in a clockwise direction. MONΞ rotates with the planetary orbital speed --- once a year in the case of the Sun --- anti-clockwise. The epicycle EZHK rotates at a speed specific to the planet, in this case, for the Sun, once a year clockwise.With the motion of the epicycle's center on the deferent from M to O, the epicyclic circle is oriented so that E remains outermost and towards the zodiacal point B. The Sun, located on the epicycle initially at E, rotates 90° to the point K, which is the uppermost point on the epicycle when its center is at O. This combination of motions continues from quadrant to quadrant through the year, at the end of which the solar epicycle will return to M and the Sun on the periphery of the epicycle will return to point E. But as the annual motion of the Sun occurs, the appearance from the earth, at the center of the deferent and zodiacal circles, is that the Sun moves faster from K to H and H to Z than it moves from E to K and Z to E. This appearance of varying speed can be understood by noticing that from E to K and from Z to E the Sun seems to move slower than the center of the solar epicycle from M to O and from Ξ to M; conversely from K to H and from H to Z the Sun seems to move faster than the center of the epicycle from nO to N and from N to Ξ. And the Sun at H is closest to the earth and at E is farthest from the earth during the annual motion. All this is as seen from the earth, and the motions of the circles remain uniform.

description: Bounded Elongation of Venus Epicyclic: The manuscript diagrams for this text are often confusing, and it is less easy to categorize them than the diagrams for the previous text, which gives the observational account of Venus's elongation. As the text says, the epicyclic explanation builds upon the immediately preceding text that describes the visible elongation. However, with the positions of X and K already misplaced in most of the diagrams for the prior text, any attempt to add an epicyclic circle for Venus would usually result in further error. Nonetheless, certain scholars of the eleventh century did reconstruct the diagrams correctly from the text. The epicyclical account of Venus's elongation prescribes a circle cutting the zodiacal radius XKB. This radius passes from the earth through the Sun at K, but the distance from X to K is nowhere stated. While it would seem proper to make this radius bisect the epicyclic circle, the location of K is possible at the center of the epicycle, below this center, or completely outside and below the epicycle. The last option would fit Plato's planetary order, which has Venus farther than the Sun from the earth. In any case, Calcidius does not specify the location of K with respect to the epicycle. The main purpose of the epicycle is not to show the order of planets but to show the limited movement of Venus with respect to the Sun, and the account does this. The epicycle ΔEZH is drawn into the preexisting diagram for the simple phenomenal description so that the epicycle fits between the zodiacal circle ABΓ and its center X and is tangent to the two preset radii XA and XΓ, which pass to points 50° to either side of the zodiacal point B.

description: Length of Seasons: The description in the text and the diagrams in the manuscripts coincide well. The purpose of the diagram is solely to show that the four equal quadrants of the zodiac contain four unequal lengths of the year and what those lengths are. Initially the circle of the twelve signs is laid out, usually within a circular band, sometimes on the outside of a single circle. The four cardinal points ABΓΔ are set anti-clockwise at 90-degree intervals, beginning with A at Aries 0° and at 12 o'clock. Two perpendicular diameters connect the pairs of points AΓ and BΔ. The letter Θ appears at the centerpoint, where the diameters intersect.

title: Beagle Marine Park bathymetry data 2018

description: This resource includes bathymetry data for Beagle Marine Park (Bass Strait) collected by Geoscience Australia (GA) and the Institute for Marine & Antarctic Studies (University of Tasmania; UTAS) during the period 17 - 26 June 2018 on the RV Bluefin. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and UTAS. The purpose of the project was to build baseline information for benthic habitats in the Beagle Marine Park that will support ongoing environmental monitoring within the South-east Marine Park Network as part of the 10-year management plan (2013-2023). Data acquisition for the project was completed during three separate voyages: Phase 1 - Seabed mapping by multibeam sonar; Phase 2 - Seabed imagery acquisition by Autonomous Underwater Vehicle, and sediment sampling; Phase 3 - Survey of demersal fish communities using Baited Remote Underwater Video (BRUVs). This dataset from Phase 1 comprises 11 bathymetry grids derived from multibeam sonar data gridded at 1 m spatial resolution, covering a combined area of 364 km2. A detailed report on the survey is provided in: Falster, G., Monk, J., Carroll, A., Siwabessy, J., Deane, A., Picard, K., Dando, N., Hulls, J., Nichol, S., Barrett, N. 2019.
