Ehler is a veteran of the VOR, sailing as a member of the last all-female team Amer Sports Too in 2001-2002, while Jackson was a candidate in the training trials earlier this year.
Both join an already record-breaking Team SCA squad that's set to make a big mark among the racing fleet come October 2014.
The new appointments now bring Team SCA's complement to seven, with four spots lets to fill, just over a year ahead of the first leg in the 12th running of the round-the-world yachting challenge.
In other VOR news, Cape Town in South Africa has been selected as the first stopover in next year's race after plans to visit Recife in Brazil were scuppered by the withdrawal of the local team from the competition.
“It is of course disappointing not to go to Recife in this edition but Brazil is very well represented in this race including a stop in Itajaí,” said Volvo Ocean Race CEO Knut Frostad.
Cape Town's waterfront is more than able to step in as a replacement, however, having hosted the race on 10 previous occasions.
