Finally, the new chapter of Ao no Calanque is out. As publication changed to Comic Spica, the new chapter isn't available online anymore.
Update: Took me half of the night to figure it out: It's possible to get an online version via binb:http://binb-store.com/index.php?main_page=product_info&products_id=13617&keyword=comic
Price is 500 Yen (should be about 6-7$) for the whole issue, viewing seems to be limited (only 2 months available). They do accept credit card, webmoney and paypal.
