"... Pliny wants to assure us that 'the whole sea is conscious of the rise of that star, as is most clearly seen in the Dardanelles, for sea-weed and fishes float on the surface, and everything is turned up from the bottom'. He also remarks that at the rising of the Dog-Star the wine in the cellars begins to stir up and that the still waters move ..." (Hamlet's Mill)

The Deluge is caused by Sirius, we can guess, and the location must be where the 'hour-glass' is turned upside down. One example of sea-weed is iri-are (as in Roto Iri Are, the 13th kuhane station):

Roto

1. Inside. 2. Lagoon (off the coast, in the sea). 3. To press the juice out of a plant; taheta roto pua, stone vessel used for pressing the juice out of the pua plant, this vessel is also just called roto. Roto o niu, east wind. Vanaga.

1. Marsh, swamp, bog; roto nui, pond; roto iti, pool. 2. Inside, lining; o roto, interior, issue; ki roto, within, into, inside, among; mei roto o mea, issue; no roto mai o mea, maternal; vae no roto, drawers. Churchill.

Iri

1. To go up; to go in a boat on the sea (the surface of which gives the impression of going up from the coast): he-eke te tagata ki ruga ki te vaka, he-iri ki te Hakakaiga, the men boarded the boat and went up to Hakakainga. 2. Ka-iri ki puku toiri ka toiri. Obscure expression of an ancient curse. Vanaga.

Iri-are, a seaweed. Vanaga.

If we move across the equator the sky will be turned upside down. Sirius could be the star to look for when the 'season of land' turns into a 'season of sea'. The 12th kuhane station is Hatinga Te Kohe, the time when the 'staff is broken'. The sky roof will collapse and darkness will engulf us. Hatinga Te Kohe appears to be a mirror image of the 'arrow of light'.
