Assuming an average salinity of 35 from the ocean and 0 for the melting ice (which is not really the case), then the salinity will drop by around 0.5. | |

(AIUI sea ice has somewhat lower salinity than the oceans, but I don't know whether the magnitude of the difference, and the tonnages of water involved, make it matter?) | |

At typical salinity, water freezes at about −2 °C. It can be even slightly colder. See Figure 3.1 of Talley et al., 2007 book (booksite.academicpress.com/DPO). Chapter 3 shows up in Google if you do a search for "maximum density seawater". | |
