It's a late answer but I was surprised nobody cited this:

Titan Mare Explorer (TiME)

The TiME lander was a part of cooperative NASA-ESA mission TSSM. The mission was not considered as highest priority by Planetary Decadal Survey 2013 so it's not being implemented now. Also it was studied as standalone Discovery class mission.

ASRG generator was planned as compact energy source but its developmend didn't end well enough.

Goals and instruments:

Goals:

• Understand Titanʼs methane cycle through study of a Titan sea.

• Investigate Titanʼs history & explore the limits of life

Instruments:

• Meteorology & physical properties (MP3)

• Mass Spec for Lake Chemistry (NMS)

• Descent and Surface Imaging Cameras
